Re: gcc 4.1.0 NOT built on i686-pc-linux-gnu (Scientific Linux 3.0.4)

The MPFR version distributed with GMP 4.1.4 is old, very buggy, and
no longer maintained. It is highly recommended to compile GMP without
MPFR support and compile the latest MPFR version separately. You can
get it here:

http://www.mpfr.org/mpfr-current/

that information has been extremely useful. actually, yesterday I had to bootstrap 4.1.0 on the platform with the oldest glibc and using 3.4.5, because compiling mpfr with 4.1.0 and using --with-mpfr-dir= triggered errors from the (old and buggy) mpfr header files.


now I have downloaded libmpfr.2.2.0.tar.bz2 (no patches available), compiled gmp and mpfr with gcc 4, and used --with-gmp-dir to bootstrap 4.1.0 successfully.

the only trouble is that the tree generated unpacking and compiling libmpfr.2.2.0.tar.bz2 is not compatible with what --with-mpfr-dir expects, so that configure exits; I had to copy the mpfr include files in foo/include, the libraries in foo/lib and use --with-mpfr=../../foo .
