MACRO exclusion

[karthik.naig]

Hi,

I am porting some code and I need to exclude all macros defined with
__STDC__ . How do I do this using gcc?? Is there any change I can make
in the makefile?

Thanks and Regards,
Karthik.

#undef _STDC_
#include <filewithevilmacrosinit.h>

What exactly do you mean by "all macros defined with __STDC__"? Can
you give some examples?

I realised this after I had posted.
I'm not sure undefining the macro is the real answer.

That's difficult to say if you don't tell us the real question.
