OK, my man page for dlopen (on Solaris) starts as

NAME
     dlopen, dlmopen - gain access to an executable object file

SYNOPSIS
     cc [ flag ... ] file ... -ldl [ library ... ]
     #include <dlfcn.h>
     #include <link.h>

Are there any 'include' directives mentionned in yours, or any library
(-ldl) ? If not, try to remove the line

#include <dlfcn.h>

in config/has_dlopen.c. If the file then compiles OK, you can remove
the same line in src/gp/highlvl.c and (presumably...)

 Configure; make bench

will work!

How many lines are there in this diff file ? (wc -l program-sta.dif)

Thanks,
