[kencu (Ken)]

In ea9528e1a577fce8ccbcec8f8a86e3197be5831a/macports-ports (master):

py-cffi: fix build on older systems

blacklist older gcc versions that don't allow

pragmas inside functions

remove a -iwithisysroot command that points to

/usr/include/libffi, which we never want,
and which is not accepted by gcc
