boehmgc @ 7.4 patch commit that fixes alloc_size warnings

Port: boehmgc

Description

I would like to propose patching a commit in master branch of boehmgc into the port:

​https://github.com/ivmai/bdwgc/commit/b725923951d77f5c6792c2797f89179267c58c9c

This commit will fix the following warning message: 

/opt/local/include/gc/gc.h:804:23: warning: unknown attribute
'__alloc_size__'
     ignored [-Wunknown-attributes]
GC_API GC_ATTR_MALLOC GC_ATTR_ALLOC_SIZE(1) void * GC_CALL

where it appears because newer versions of clang has no longer supported alloc_size attribute. These warning messages have unnecessarily contaminated my debugging environment, with almost 100 appearances in one compiling session. I would greatly appreciate that the mentioned commit is patched into the official boehmgc port.

I am using Xcode 7.1 on OS X El Capitan, with Apple LLVM version 7.0.0 (clang-700.1.76).
