commit 6ca3ab621cd9e5054a47b5946dacd98df756a879
Author: Michael Gran <spk121@yahoo.com>

    don't presume availability of gmp.pc
    
    This suggests moving the conditional that determines if mini-gmp is used
    into scmconfig.h.
    
    * configure.ac: replace PKG_CHECK_MODULES for gmp with AC_LIB_HAVE_LINKFLAGS
        Remove ENABLE_MINI_GMP define.  Also don't run mpz_inits test for
        --enable-mini-gmp.
    * libguile/gen-scmconfig.c (main) [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
        with SCM_I_GSC_ENABLE_MINI_GMP
    * libguile/bytevectors.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
        with SCM_ENABLE_MINI_GMP
    * libguile/init.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
        with SCM_ENABLE_MINI_GMP
    * libguile/numbers.c: include scm.h
        [SCM_ENABLE_MINI_GMP]: provide mpz_inits and mpz_clears
        [ENABLE_MINI_GMP]: prefer SCM_ENABLE_MINI_GMP to ENABLE_MINI_GMP
    * libguile/numbers.h: include scm.h
    * libguile/random.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
        with SCM_ENABLE_MINI_GMP
    * libguile/socket.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
        with SCM_ENABLE_MINI_GMP
