The "yes" here, by virtue of not being a path, means that the autodetect
code found your Krb5 headers in the default include path.  We've had
problems with Solaris before because it is distributed with the Krb5
headers installed by default, but not the libraries.  So, the autodetect
code, and thus the compiler, could be finding the Solaris headers rather
than the MIT K5 ones.  Try configuring with

Again, _which_ gssapi.h?  You'll notice in, config.h, and

/* Define to an alternative value if GSS_C_NT_HOSTBASED_SERVICE isn't
in the gssapi.h header file.  MIT Kerberos 1.2.1 requires this.  Only
when using GSSAPI. */

If GSS_C_NT_HOSTBASED_SERVICE didn't get defined by configure in your
config.h, then the configure script either found the string in one of the
files, or didn't find one of its known alternatives.  Ah, here it is, it
found it:

> checking for GSS_C_NT_HOSTBASED_SERVICE... yes

So, again, the autodetect code probably found the Solaris headers.

The file is lib/xgssapi.h.  I include it rather than including all the
GSSAPI headers directly to consolidate and hide some of the #ifdef
<HEADER_EXISTS> magic that was appearing repetively in various source files
and complicating maintenance.

Yep.  Looks like MIT K5.  The dir you want to pass to configure with
--with-gssapi= should be the dir you were in when you did that `nm' minus
the `/lib' part.
