Paths to system header files

There are some environment variables you can use, e.g, CPATH, etc. Please
take a look at the Environment section of this page for details, or look at

Sorry, don hinton. I didn’t see your message. Anyway, it doesn’t work. I tried using these variables some time ago and I have used them again now, and “limits.h” is not found:

#if defined GNUC && !defined GCC_LIMITS_H
/* `GCC_LIMITS_H’ is what GCC’s file defines. */

include_next <limits.h>


That’s the problematic line in /usr/include/limits.h in my case.
