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