CPP problem

[Alexander Mojaev]

Hi Damjan,

i have this problemm too.

in my case:

x.h:

#ifndef _X_
#define _X_
#define Y 1
#endif

y.h:

#ifndef _Y_
#define _Y_
#define Y 1
#endif

z.c:

#include <x.h>
#include <y.h>

void main()
{
    return X + Y;
}

After cpp processing with "gcc z.c -I../../c/bug -E" :

void main()
{
    return 1  + Y;
}

but with "gcc z.c -I. -E" it works fine. ../../c/bug/ = ./

gcc z.c -I../../c/bug --trace-includes
../../c/bug/x.h
../../c/bug/y.h
z.c: In function `main':
z.c:6: `Y' undeclared (first use in this function) ...


Only when installed in AFS causes this bug. 

I think, that is a egcs preprocessor problem, because
with old gcc -v 2.7.2.3 (RedHat 5.2) it works correctly.

Regards,
