Linux 1.3.15, gcc 2.7.0, ELF.

The message from config.log is:
/tmp/cca194791.o(.text+0x14): undefined reference to `lstat'

The problem seems to be in the AC_CHECK_FUNCS macro.  Zsh's configure,
which says it is from autoconf 2.10, produces a conftest.c containing
the equivalent of:

char lstat();
int t() {
 lstat();
 return 0;
}

If I look at a different software package whose configure was generated by
autoconf 1.11, the code is:

int t() {
 extern char lstat(); lstat();
 return 0;
}

This latter compiles successfully and thus defines HAVE_LSTAT.

So just exactly who is wrong here?  autoconf?  gcc 2.7.0?

In any case, I suggest the following change to glob.c, just to prevent the
(@) glob modifier from producing wildly inaccurate results when configure
makes this kind of error.
