[cfe-dev] clang and boost

[Reid Kleckner]

IIUC the issue is that clang masquerades as gcc 4.2.1 to match
llvm-gcc, setting __GNUC__, __GNUC_MINOR__, and GNUC_PATCH_LEVEL__ to
4, 2, and 1.  However, Mark doesn't happen to have gcc 4.2.1's
headers.  Boost seems to be attempting to include specifically the
headers that go with the version of the compiler being used.  Clang
will attempt to use the latest gcc headers installed.  Anybody know
why?  IMO this logic should be disabled ifdef __clang__.
