Did some tests with current versions of both 3.0 branch and mainline
for DJGPP

Due to some latest changes in gcc $DJDIR/include got scanned before 
gcc specific header directory and as result  I got DJGPP stddef.h 
included instead of gcc one. The result were compiler errors about 
undefined size_t. (NOTE:  gcc-3.0.2 binaries in v2gnu are Ok and 
there is no similar problem).

We can undefine PREFIX_INCLUDE_DIR in gcc/config/i386/djgpp.h so
this directory will not be searched before GCC own header dir

I think that this behaviour is bug as it eliminates anything 
fixincludes is doing when fixing non GCC headers to be compatible.
So it should be fixed in GCC

Of course we could additionally safeguard us by protecting our
stddef.h. stdarg.h from gcc-3.X:

#if __GNUC__>=3
#include_next <stddef.h>
#else

old contents of stddef.h

#endif /* __GNUC__>=3
