This is basically the same configure script that I have been using for
two years, so I doubt that it will cause problems.

The limits.h file in /usr/lib/gcc-lib/../include/ *is* the one that is
supposed to be used.  It includes the /usr/include/limits.h file
automatically.

Are you saying that when I announced that the limits.h problem was
fixed, I was wrong?  I specifically checked the -E output from a
program and saw that /usr/include/limits.h was pulled in specifically.
