930 Some influential environment variables:
931 CC C compiler command
932 CFLAGS C compiler flags
933 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
934 nonstandard directory <lib dir>
935 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
936 headers in a nonstandard directory <include dir>
937 CPP C preprocessor
938 GMPLIBS How to link GMP
939 GMPINC How to find GMP include files
