You have added the flag gcc -std=gnu99, which according to the gmp.h  
header in GCC 4.3 later implements ISO C99 inline semantics, unless - 
fgnu89-inline is used. When I took away that flag from the five  
occurrences in the Makefile in libguile/, then it compiled and  
installed.

I have GCC 4.0.1. So for some reason, on this compiler, the flag seems  
causing the GMP inline functions to be added as ordinary functions,  
causing the linking problem between the copies.
