Comment 7 for bug 227686

testcase: pick any package building an extension, e.g. python-imaging. Without this patch the default options -fno-strict-aliasing and -fwrapv are not seen for python2.5 builds, with this patch these are included on the command line, and additionally specifying CFLAGS to another value (.e.g -O3) works as expected (it's appended after the default CFLAGS). checked on i386 hardy, and hardy-proposed.
