Working on FreeBSD8.1, in a jailed environment. I have an ancient

During the make process, I get the following error:

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.

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

You could attempt to configure and build those prerequisites separately
in place where download_prerequisites put them (making a clean build
directory for each), to get an idea more easily what the issues might
be. Inability to complete these individual builds would block the gcc
build.
