I'm afraid I don't understand from your report why this fails, and I
can't test it myself since I don't have a Linux system on which to try
it.  Do you mean that on your Linux system, DLSYM_ADDS_USCORE is being
defined even though dlsym requires a leading underscore?  Or is
DLSYM_ADDS_USCORE defined correctly, but the code in sysdep_dynl_func
doesn't do the right thing?

I don't have X11 or Marius's test-gtk.scm, either, so I can't use this
information to diagnose the problem.

If you give me enough information to reproduce the problem, then I can
solve it.  But I can't reproduce the problem without running it on a
Linux box, so I need a little more assistance from you.  One thing
that would help is code from test-gtk.scm that calls "dynamic-link" or
"dynamic-call", so I know whether Linux's dlsym requires a leading
underscore or not.  If you can tell me whether the configure test
appears to be doing the right things or not, that will also be useful.
