[cfe-dev] Clang tutorial

[Simone Pellegrini]

Hello,
thanks for the example but this is what I am currently doing in my program.

The problem is that every time I include some header like stdio.h in my 
code I get this error from the parser:

Adding /home/spellegrini/shared/openmpi-1.3.2-gcc433/include
** Parsing file: bench/example.c **
initialize
In file included from bench/example.c:7:
/home/spellegrini/shared/llvm/lib/clang/1.0/include//stdarg.h:29:9: 
error: unknown type name '__builtin_va_list'

This was not happening with previous versions of CLANG, so what has been 
changed? What's the problem with this __builtin_va_list??
How can I make clang able to parse it without complaining?

cheers, Simone
