Hello,

By examining the code in both /usr/local/include/gc.h and libguile/pairs.h I managed to resolve the problems.

I did this by adding two lines to gc.h, at the top of the file.

#define HAVE_GC_IS_HEAP_PTR              // OSJ
#define HAVE_GC_MOVE_DISAPPEARING_LINK   // OSJ

This is maybe not your preffered solution, but I managed to compile and link the libraries and programs. Hopefully this helps you.

Best regards,
