[cfe-dev] Is is possible to use ParseAST() without adding the clang predefines?

[Paolo Bolzoni]

dear cfe-list,

I use clang as general purpose parser, I'd like to be able to set the
predefines of other compilers instead of clang's ones.

But it seems that ParseAST() unconditionally calls DefineBuiltinMacro().
This adds macros that we could undefine (knowing their names), but it also
adds a typedef that is on the way. Is this avoidable?

Thanks,
pb
