[tree-ssa] Problems building fortran (gmp) with latest cvs-version

[lsjoberg at aland dot net (Linus Sjöberg)]

In FreeBSD 4.8-STABLE I have two versions of libgmp. The system one in
/usr/{lib,include} which is too old for compiling gcc (see below) and a
fresh one in /usr/local/{lib,include} which should be new enough (installed
with the ports system).

The problem is that gcc seems to use the /usr/{lib,include}-one instead for
the version within /usr/local/{lib,include} with the following result:

gcc   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -fno-common   -DHAVE_CONFIG_H  -o f951 \

I modified the Makefiles a bit so that they inserted a -I /usr/local/include when
compiling and i -L /usr/local/lib when linking so that it used the correct version
of libgmp but got an ICE in stage 2. This could be a result of me messing with 
the wrong parts of the Makefiles so I wouldn't make too much of it at the moment.
