Subject: limits.h problem in cross-toolchain

In my linux hosted cross-djgpp toolchains, gcc-provided limits.h doesn't
include_next the djgpp-provided limits.h, I have to manually correct it.
cross-gcc is configured like:
../gcc-3.46/configure --prefix=/usr/local/cross-djgpp
--target=i586-pc-msdosdjgpp
--with-headers=/usr/local/cross-djgpp/i586-pc-msdosdjgpp/include
--enable-languages=c,c++ --disable-libgcj --disable-libada
--disable-nls

Same thing happens with gcc 3.3.6 and gcc 5.1.0 too.  Before configuring
and building gcc, djgpp libs and headers are of course copied under
/usr/local/cross-djgpp/i586-pc-msdosdjgpp/

$ cat t.c
#include <limits.h>
#ifndef PATH_MAX
#error bad limits.h
#endif

If I don't correct the installed gcc limits.h myself, the above test surely
errors, which is annoying.  What am I missing?
