macosx extern inline problem

[Jay K]

This is the default gcc with MacOSX 10.5/x86. I think it is worth trying a bit.
There is seemingly just one problem, here is a fix:

gmp-h.in:

#ifdef __GNUC__
> /* Apple gcc 4.0.1 -std=gnu99 has problems, worked around here. */
> #if defined __GNUC_STDC_INLINE__ && defined __APPLE__ && __GNUC__ == 4 && __GNUC_MINOR__ == 0
> #define __GMP_EXTERN_INLINE      __inline__
> #define __GMP_INLINE_PROTOTYPES  0
> #else
#if (defined __GNUC_STDC_INLINE__) || (__GNUC__ == 4 && __GNUC_MINOR__ == 2)
#define __GMP_EXTERN_INLINE extern __inline__ __attribute__ ((__gnu_inline__))
#else
#define __GMP_EXTERN_INLINE      extern __inline__
#endif
#define __GMP_INLINE_PROTOTYPES  1
#endif
> #endif

static inline would maybe work too. I can try that.

It sounds like if you kept everything in C and accepted the default PIC, many problems would go away?
"Keeping everything in C", the use of "none" above, is what the gcc build does when it builds gmp.

With the above patch, my script works:

#! /usr/bin/env bash

set -e
set -x

gmp_VER=4.3.2
mpfr_VER=2.4.2
mpc_VER=0.8.1
build=i686-darwin
gmp_packages="gmp mpfr mpc"

# native gmp, mpfr, mpc

for T in $build; do
  for P in $gmp_packages; do
    mkdir -pv /obj/$P/$T
    cd /obj/$P/$T
    if [ -f Makefile ]; then :; else
      /src/`eval echo $P-\$\{${P}_VER\}`/configure \
        -host=none-none-none \
        -target=none-none-none \
        -disable-shared \
        -with-gmp=$HOME/$T \
        -with-mpfr=$HOME/$T \
        -with-mpc=$HOME/$T \
        -prefix=$HOME/$T \
        -verbose
    fi
    make -j8
    make install
  done
done


Thanks,
