>Description:
If I use clang to build python2.7, I get the following output from
python2.7-config --cflags
-I/usr/local/include/python2.7 -I/usr/local/include/python2.7 -fno-strict-aliasing -OPT:Olimit=0 -O2 -pipe -fno-strict-aliasing -DNDEBUG -O2 -pipe -fno-strict-aliasing
Note the `-OPT:Olimit=0'
If I use GCC4.2 from the base I don't have this:
-I/usr/local/include/python2.7 -I/usr/local/include/python2.7 -fno-strict-aliasing -O2 -pipe -fno-strict-aliasing -DNDEBUG -O2 -pipe -fno-strict-aliasing
I built the port twice with clang. Got the same results.
This is problematic, because all ports using python2.7-config to get their
CFLAGS won't build.
I would guess this line is the culpritm but I didn't investigate:
CONFIGURE_ENV+= OPT="${CFLAGS} ${_PTH_CPPFLAGS}"
Note this problem does not seem to exist with Python 3.2
