Excellent!

Too bad Audacity had a bug, too; maybe we should release 1.2.0-pre3
after we have the VST enabler working too.

"so" stands for "shared object", which is the Unix equivalent of
a DLL.  I think that the naming convention is that gverb*.so.c contains
the plug-in "main" function and LADSPA code, while all of the other
gverb files contain gverb-specific functions.  Simple plug-ins just
throw everything in one file, but gverb also exists as a library
somewhat independent of LADSPA.

But if you got it to work, you must have included some sensible
collection of files.

I ran into similar issues on the Mac, though I didn't realize that
fabsf is defined for C++ - I thought it was part of C99.  Either
way, functions like that need to be wrapped so that LADSPA plug-ins
can be made more portable.
