* cfg.mk (sc_prohibit_strncmp): New rule, mostly from libvirt.
* src/system.h (STREQ_LEN, STRPREFIX, STRNCMP_LIT): Define.

gcc that char_to_repeat is not used uninitialized.

This valid translation spec aborted:
LC_ALL=en_US.iso-8859-1 tr '[:upper:]- ' '[:lower:]_'
This invalid translation spec aborted:
LC_ALL=en_US.iso-8859-1 tr '[:upper:] ' '[:lower:]'
This was caused by commit 6efd1046, 05-01-2008,
"Avoid tr case-conversion failure in some locales"
This misaligned conversion spec was allowed:
LC_ALL=C tr 'A-Y[:lower:]' 'a-z[:upper:]'
This was caused by commit af5d0c36, 21-10-2007,
"tr: do not reject an unmatched [:lower:] or [:upper:] in SET1"
This misaligned spec was allowed by extending the class:
LC_ALL=C tr '[:upper:] ' '[:lower:]'
* src/tr.c (validate_case_classes): A new function to check
alignment of case conversion classes. Also it adjusts the
length of the sets so that locales with different numbers of
upper and lower case characters, don't cause issues.
(string2_extend): Disallow extending the case conversion
class as in the above example. That is locale dependent
and most likely not what the user wants.
(validate): Do the simple test for "restricted" char classes
earlier, so we don't redundantly do more expensive validation.
(main): Remove the case class validation, and simplify.
* tests/misc/tr-case-class: A new test to test the various
alignment and locale issues, associated with case conversion.
* tests/misc/tr: Move case conversion tests to new tr-case-class.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the fixes.

Following on from commit dae35bac, 01-03-2010,
"sort: inform the system about our input access pattern"
apply the same hint to all appropriate utils.
This currently gives around a 5% speedup for reading
large files from fast flash devices on GNU/Linux.

Use this command:
git ls-files | grep -v COPYING \
| xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \
build-aux/update-copyright

* src/system.h: Rename emit_bug_reporting_address() to
emit_ancillary_info() and update it to not print the translation
project address in en_* locales, and _do_ print it in the 'C'
(and other) locales so that it's included in the default man page.
Also mention how to invoke the texinfo documentation for each command.
Also move the "hard-locale.h" include to the 8 files that now use it.
* man/help2man: Strip the newly added texinfo reference from the
--help output as a more verbose version is already added by help2man.

In 1463824d8e7f72c31f1d803d7cfe2b608ccafc5c, I added some

Aborted
(N_CHARS, N_CHAR_CLASSES): Now an enum, not a macro.
This is safe since the code already assumes N_CHARS fits in int.
(Filter): Remove: we want to prototype everything.
(ORD, CHR): Remove. All uses removed. Some replaced with:
(uchar): New function. All places where a char must be converted
to an unsigned char are now done this way, not by ad-hoc methods.
(count): New type. Use it whenever counts or states are needed.
(BEGIN_STATE): Increase from INT_MAX - 1 (which was bogus, anyway,
since we used it in an unsigned int context) to UINTMAX_MAX - 1.
(REPEAT_COUNT_MAXIMUM): New macro. Use it in place of BEGIN_STATE
whenever appropriate.
(NOT_A_CHAR): Remove global macro; now a local enum.
(UL_LOWER, UL_UPPER, UL_NONE): No longer specify values, since
the rest of the code no longer depends on them.
(class_ok): Remove; all uses changed to use inline comparisons.
(RE_NO_TYPE): Remove; wasn't used or needed.
(struct List_element): normal_char and equiv_code are now unsigned
char, not int.
first_char, last_char, and the_repeated_char are now unsigned char,
not unsigned int. repeat_count is now count, not size_t.
All uses changed.
(struct Spec_list): state is now count, not unsigned int.
lengthis now count, not size_t.
n_indefinite_repeats is now size_t, not int.
has_equiv_class, has_char_class, and has_restricted_char_class
are now bool, not int. All uses changed.
(struct E_string): s is now char *, not unsigned char *.
escaped is now bool *, not int *. All uses changed.
(ES_MATCH): Remove macro, replacing with:
(es_match): New inline function. All uses changed.
(squeeze_repeats, complement, posix_pedantic, truncate_set1,
translating): Now bool, not int.
(io_buf): Now char array, not unsigned char.
(SET_TYPE): Remove. All uses replaced with bool.
(is_equiv_class_member, unquote, append_range, append_char_class,
append_equiv_class, find_closing_delim, star_digits_closebracket,
build_spec_list, parse_str, homogeneous_spec_list):

(is_equiv_class_member, is_char_class_member, make_printable_str,
append_normal_char, append_range, append_repeated_char,
get_s2_spec_stats):
Args are now of proper integer type.
(unquote, look_up_char_class, make_printable_str,
append_equiv_class, build_spec_list, squeeze_filter):
Avoid unsigned char *p; gently convert *p to unsigned char instead.
(unquote, get_spec_stats): Do not jump past declarations and then
use them; C doesn't allow this in portable programs.
(make_printable_str): Check for overflow in size calculations.
(xmemdup): Remove. All uses rewritten.
(find_bracketed_repeat): Args are now of proper pointer-to-integer
type. Do not reject [c*0]. Use xstrtoumax, not xstrtoul.
(find_bracketed_repeat, star_digits_closebracket): Check that the
digits are not escaped.
(build_spec_list): Don't bother to copy opnd_str; not needed.
(build_spec_list, get_next): Simplify internal logic a bit.
(card_of_complement): Fix bug due to char overflow.
(get_spec_stats): Don't assume len fits into int.
Check for integer overflow. Use abort() rather than assert(0).
(string2_extend): Fix subscript error: is_char_class_member (..., 255)
was being invoked.
(squeeze_filter): READER is never null now; simplify code.
READER arg now has a simpler type. Remove unnecessary casts.
(squeeze_filter, main): Calls to fwrite improperly checked result
against zero, rather than against requested size.
(plain_read): New function.
(read_and_delete, read_and_xlate):
Remove unused filter arg, and don't worry about hit_eof.
Simplify by using plain_read.
(set_initialize): Args are bool and bool *, not int and SET_TYPE *.
(main): Always pass a non-null procedure to squeeze_filter.
Rewrite so that class_ok isn't needed.

(card_of_complement): Use cleaner `sizeof in_set'
rather than `N_CHARS * sizeof(in_set[0])'. Using HPUX's /bin/cc
(aC++/ANSI C B3910B A.05.55 [Dec 04 2003]) on an ia64-hp-hpux11.22
system, those two expressions are not the same (256 vs. 1024).
The effect of this problem was that `tr -c x y' would fail:
tr: when not truncating set1, string2 must be non-empty

for portability to EBCDIC hosts.

a loop initializing the just-allocated memory to zero.
|
|
(usage): Don't bother normalizing exit status
since the arg is already the correct exit status now.
(FATAL_ERROR, main): Exit with status EXIT_FAILURE, not 2, on errors.

|
|
(append_repeated_char, append_equiv_class, spec_init): Use more maintainable
and usually-shorter `sizeof *var' rather than `sizeof EXPLICIT_TYPE'.
