[cfe-commits] r98003 - /cfe/trunk/lib/Headers/stdarg.h

New Revision: 98003

URL: http://llvm.org/viewvc/llvm-project?rev=98003&view=rev
Log:
Place the definition of 'va_list' within a preprocessor guard.  This matches the behavior of GCC, and avoids potential conflicts with system headers (e.g., stdio.h).  Fixes <rdar://problem/7727145>.
