Tweak configure to attempt to add -qnoansialias to CFLAGS whenever running on AIX with a non-gcc compiler. The previous coding would do this only if CC was exactly "xlc"; which is a bad idea, as demonstrated by trouble report from Mihai Criveti. 2009-02-11 21:02:40 +01:00			`# Set appropriate default compiler options if using xlc`

Rename templates to match names in makefiles/Makefile.* and include/port. Read templates after compiler is detected. Convert all templates to real shell scripts. Rename bsd->openbsd, alpha->osf. 2000-07-15 17:54:52 +02:00			`case $host_os in`

Don't bother adding to cflags/cppflags, just set them because configure handles that, and make solaris debug use no optimization. 2004-12-02 19:11:40 +01:00			`CFLAGS="-O -qmaxmem=16384 -qsrcmsg"`

Allow MEMSET_LOOP_LIMIT to be set on a per-platform basis, and turn off MemSet on AIX by setting MEMSET_LOOP_LIMIT to zero. Add optimization to skip MemSet tests in MEMSET_LOOP_LIMIT == 0 case and just call memset() directly. 2006-02-03 14:53:15 +01:00
