Working on FreeBSD8.1, in a jailed environment.  I have an ancient
(gcc3.4.6) version of gcc that works as my C compiler.  gmake version 3.8.1

One I hit a problem with that make version and I had to upgrade to
3.8.2.  Dunno remember the exact problem.

I do the following, as root:
tar zxf gcc-4.7.1.tar.gz cd gcc-4.7.1
ls -atlG contrib/downl*
./contrib/download_prerequisites    <-- seems to work

This should generate soft links gmp, mpc, mpfr to the respective,
just downloaded source packages.

./contrib/download_ecj              <-- seems to work
 cd ..
 mkdir obj_gcc471
 cd obj_gcc471
 ../gcc-4.7.1/configure     <-- runs successfully.

Read what gmp, mpfr, mpc is uses in its output or config.log.

 gmake

During the make process, I get the following error:

checking for math/rint... yes
checking for long double... yes
checking format of `long double' floating point... IEEE extended, little
endian
checking for gmp.h... no
configure: error: gmp.h can't be found, or is unusable.
gmake[2]: *** [configure-stage1-mpfr] Error 1
gmake[2]: Leaving directory `/usr/src/local/obj_gcc471'
gmake[1]: *** [stage1-bubble] Error 2
gmake[1]: Leaving directory `/usr/src/local/obj_gcc471'

N.B., gmp.h is *not* present anywhere in gcc-4.7.1 after the
download_prerequisites.  Should it be?

Yes, follow the gmp soft link in GCC's top level sources as
mentioned above.

Any help is appreciated,

Thanks.
