# We'll never use the old pgcc-2.95.1 with the buggy -O3, so having
# the -O3 that is originally used should work.
# Substitute the -O2 to -O3 because I'm not sure if simply appending
# it will preserve(not override) the detailed opt flags used in RPM_OPT_FLAGS:
CFLAGS="`echo $RPM_OPT_FLAGS|sed 's/-O2/-O3/'` -DPNG_SKIP_SETJMP_CHECK" \
