ive tried compiling without the CFLAGS and that also causes the same error.

Jordan:  do you see the part where you paste: glibc-2.3.2_pre1-r0

Please dont mark these reports 'CRITICAL' okay?

Apparently we can use an preprocessor def to fix it.

adding -DHAVE_ERRNO_AS_DEFINE=1 to CFLAGS seems quick & painless

i'll be adding 4.0.11a with this fix shortly.

I added this to mysql-3.23.55.ebuild :

+       #glibc-2.3.2_pre fix; bug #16496
+       export CFLAGS="${CFLAGS} -DHAVE_ERRNO_AS_DEFINE=1"

that should fix you up, I think.
