This - and every other variations on this I tried - failed.
In fact, it looks like what this does is simply writes the 4th argument of the
macro to a text file, above a "#include <openssl/ssl.h>", and attempt to
preprocess and compile the file. This fails, probably because krb5.h (and other
kerberos includes) are included in ssl.h by "#include <krb5.h>", and
/usr/kerberos/include/ is not one of the standard paths for header files.
However, I found this to work :
--- configure.in.orig 2003-08-14 11:52:36.000000000 +0200
+++ configure.in 2003-08-14 11:59:53.000000000 +0200

With these changes, it does configure, compile, and run fine, with openssl
enabled ;-) !
I have no clue why the kerberos include files are not in one of the standard
locations (is that specific to RH 9 ?).
I tried putting the above changes in a redhat-only section, so I hope it does
not break configure for other distros / platforms (this probably needs testing,
but I don't have the ressources to do it myself).
Thanks a lot for you help, Burton.
