base system is lfs, compiled in february 08 with kernel 2.6.24
no 64bit compiler or library

the cpu is 64bit capable

i recompiled again without ABI=32 and found the above message.

then i recompiled without CFLAGS and gmp compiled fine.

there are other packages where the book warns about CFLAGS, thus i think 
it would be fine to add a warning with gmp too.

thanks for your analysis.
