I have added a new procedure `set-dynamic-load-mode!' to the current
development version, which can be used to fine-tune the way shared
objects are loaded. Gambit appears to call dlopen(2) with RTLD_NOW,
which means C symbols inside the loaded file are not exported.
Chicken uses RTLD_GLOBAL (and RTLD_LAZY), and exports symbols
so that subsequently loaded files can access the C symbols.

For the time being, you can replace the occurrence of
"RTLD_GLOBAL | RTLD_LAZY" in runtime.c with "RTLD_LAZY".
I haven't tested how this interacts with loading and core library
units, but it should work. It definitely fixes the problem with
normal shared objects loaded via "load".
