+# The optimization level here for GCC ports is set here for a reason.  It's

+# The general concensus seems to be that -O2 is the one to use.
+# Over the years, I've been told to use many different settings, including -O6.
+# In recent versions of GCC [as of 2/2005], -O6 generates bad code that, among
+# other ill effects, causes infinite loops.
+# -O3 seems to be safe, but empirical observation from our local expert
+# indicates that in some (many?) cases -O3 code runs slower than -O2.

+# Note: It is a long and disgusting story about why cc is set to ucbcc.  You
+# need to invoke the C compiler so that it links with the SVR4 libraries and
+# not the BSD libraries, otherwise readdir() will return the wrong information.
+# Of all the names in the most common path, ucbcc is the only name to be found
+# (on /usr/ccs/bin) that points to a suitable compiler.  cc is likely to be
+# /usr/ucb/cc which is absolutely not the compiler that you want.  The real
+# SVR4 cc is probably something like /opt/SUNWspro/bin/cc which is rarely in
+# anyone's path.
+#
+# ucbcc is probably a link to acc, e.g. /opt/SUNWspro/SC4.0/bin/acc, and is
+# the UCB C compiler using the SVR4 libraries.
+#
+# If ucbcc isn't on your system, then punt on the SUN C compiler and use gcc
+# instead (the gso port instead of the sol port).
+# 
+# If, in spite of all the above warnings, you choose to use the "soc" port
+# instead of the "sol" port, be sure to check the behavior of the LIST command
+# in imapd.  Also, note that the "soc" port uses -O.  If you want to use the
+# real SVR4 compiler, you must use -O.  If it works to compile with -O2, then
+# cc is probably using the UCB compiler with BSD libraries, and will not build
+# a good binary
+#
+# To recap:
+# 1) The sol port is designed to be built using the UCB compiler using the
+#    SVR4 libraries.  This compiler is "ucbcc", which is lunk to acc.  You
+#    use -O2 as one of the CFLAGS.
+# 2) If you build the sol port with the UCB compiler using the BSD libraries,
+#    you will get no error messages but you will get bad binaries (the most
+#    obvious symptom is dropping the first two characters return filenames
+#    from the imapd LIST command.  This compiler also uses -O2, and is very
+#    often what the user gets from "cc".  BEWARE!!!
+# 3) If you build the sol port with the real SVR4 compiler, which is often
+#    hidden away or unavailable on many systems, then you will get errors
+#    from -O2 and you need to change that to -O.  But you will get a good
+#    binary.  However, you should try it with -O2 first, to make sure that
+#    you got this compiler and not the UCB compiler using BSD libraries.
