I cannot try the icc compile because I have a PowerPC, but I did the gcc 
compilation.  If I understand the main() function, I should have 
seen "a bignum" at some point.  Here is a copy of the warnings and the 
output from the program itself:

gcc -Wall -Wextra -I/opt/local/include -Os -mcpu=970 -mtune=970 -mpim-altivec -mpowerpc-gpopt -g3 test.c -L/opt/local/lib -lgmp -lm -o test-gcc
test.c: In function 'bignum_hash':
