I'll do the same.  I'm not sure why that's there.  It might
be that I added it a long time ago, back when I didn't really 
grok how extensions worked, or maybe there was a time when 
using GC-related functions required this library.

I'll try to wrap these in an #ifdef in srpersist.h.

I'll add to the README to mention the sqlucode.h issues.

Please let me know how your experience with SrPersist goes.  Sorry
for all the problems compiling.  I've always compiled in a full 
source tree under both Unix and Windows, so I wasn't aware of the 
issues you faced.
