Pre-C99 build failure
-----------------------
-There is a new, implicit build requirement:
-To build the coreutils from source, you should have a C99-conforming
+In 2009 we added this requirement:
+To build the coreutils from source, you must have a C99-conforming
compiler, due to the use of declarations after non-declaration statements
in several files in src/. There is code in configure to find and, if
possible, enable an appropriate compiler. However, if configure doesn't
find a C99 compiler, it continues nonetheless, and your build will fail.
-If that happens, simply[*] apply the included patch using the following
-command, and then run make again:
-
- cd src && patch < c99-to-c89.diff
-
-[*] however, as of coreutils-7.1, the "c99-to-c89.diff" file is no longer
-maintained, so even if the patches still apply, the result will be an
-incomplete conversion. It's been 10 years. Get a decent compiler! ;-)
+There used to be a "c99-to-c89.diff" patch you could apply to convert
+to code that even an old pre-c99 compiler can handle, but it was too
+tedious to maintain, so has been removed.
