so i'm trying to get xemacs to build, and configure decides it's ok to build
modules, but when it tries to build them, it throws up at the module-link stage,
with a zillion undefined references:
make[1]: Entering directory

etc.
etc.
the problem, i assume, is that the ellcc front end is not passing the correct
flags to say "build a shared LIBRARY, damn it!" and instead it tries to build
an
executable.
here's ellcc.h:

/* Most of this is required due to a bug in the GCC compiler driver

reduces the compiler command line length, which can be a problem
on some systems. */

any module developers [jerry james?] out there have any ideas what's going on?
i confess to not understanding very well how dynamic linking and loading works.
