$ CFLAGS='-L../gmp-4.1.4/.libs -I../gmp-4.1.4' ./runbench

***** GMPbench version 0.1 *****
Using CFLAGS = "-L../gmp-4.1.4/.libs -I../gmp-4.1.4" from your environment
Using default CC = "gcc"
Using default LIBS = "-static -lgmp"
Using compilation command: gcc -L../gmp-4.1.4/.libs -I../gmp-4.1.4 foo.c 
-o foo
-static -lgmp
You may want to override CC, CFLAGS, and LIBS
Using gmp version: 4.1.4
