boehmgc 7.1 failed to build on leopard x86_64

[daitakahashi]

Since _NONSTD_SOURCE (enabled for platform darwine 9) is incompatible with __LP64__, boehmgc failed to build when x86_64 is enabled.

Some manual compilations with different flags shows that a declaration of _XOPEN_SOURCE instead of _NONSTD_SOURCE (same as platform darwin 10) solved this problem on i386 and x86_64. However, to build with -arch ppc seems to require _NONSTD_SOURCE, not _XOPEN_SOURCE (because I don't have ppc mac, I can check only a build phase).

Here is a Portfile patch. I tested it for i386 and x86_64 architectures and got universal binaries without any problems. This patch also considers the requirement of _NONSTD_SOURCE on ppc architecture (but I cannot check if it works on ppc and ppc64). Thank you very much.

This was fixed in r79740.
