pypy shouldn't need gcc45

[macporter90210@…]

At one point pypy couldn't compile with the standard gcc-4.2 included in OSX, and so it needs gcc45 port if gcc-4.0 is not available (as in Lion). That problem is now fixed, and gcc-4.2 is sufficient for pypy. Please remove the unnecessary dependency on gcc45 especially as most other ports use versions 4.2, 4.4, 0r 4.0 anyway.

Replying to macporter90210@…:

Can you provide a source for this statement? I couldn't find anything on the web site to indicate this, the 1.6 code still defaults to gcc-4.0 and has comments warning against using 4.2 or llvm, and there are issues with gcc-4.2 even on other platforms according to mailing list messages from as recently as August.

Well, its just that I installed pypy with the following patch to the Portfile, thus installing pypy without gcc45. It worked and I have a working pypy port. I am on Lion.

The default gc root finder is now shadowstack rather than asmgcc on non-Linux platforms, so that should theoretically remove the incompatibilities with certain compiler versions. In my testing however, using gcc-4.2 still breaks the build. Clang, OTOH, seems to work.

So, the gcc45 dependency is gone for 1.7 (r87473).
