Description Daniel Dunbar 2008-09-11 15:11:10 PDT 
This is a placeholder for implementing support for
preprocessor line directives.

This is apparently important for Parrot as well as
for correctly reparsing our own preprocessor output.

a little test case, which doesn't trigger any error with gcc, but clang does:

# 29 "/cvs/llvm/Debug/Headers/stdarg.h" 3 4
typedef __builtin_va_list va_list;
typedef __builtin_va_list __gnuc_va_list;
typedef __gnuc_va_list va_list;

Done!
