[cfe-commits] [PATCH] [libcxx][build] ignore unknown pragmas on GCC

[Saleem Abdulrasool]

  I can try to work out the pragmas that GCC was unhappy about (IIRC, it was the diagnostics macros that clang supports to modify warning flags for diagnostics).  However, trying to accommodate the pragmas for every single compiler is likely to get unwieldy (unless we want to handle it similarly to attributes).
