[cfe-commits] [PATCH][MS] Fix for 7968 - clang lexer cannot parse 0x6cb9a43e+(0)

[Francois Pichet]

Hi,

Patch to fix http://llvm.org/bugs/show_bug.cgi?id=7968
It is a lexer hack to be compatible with MSVC.

Allow to parse things like:
      int var = 0x6cb9a43e+0;
in -fms-extensions mode.

The fix is to not continue parsing a number pp-token when we reach a
'-' or '+' if the token was starting with '0x' or '0X'.
This removes ~250 compile errors when parsing about 1200 .h from the
Windows SDK.

Comments welcome.
