Hi Guys,
http://www.mpfr.org/mpfr-current/#changes
The current release of the MPFR library (v3.1.0) has reorganized its
sources such the mpfr.h header file is now in a sub-directory called
'src', rather than being at the top level. This has broken GCC's use
of in-tree MPFR sources.
I am asking for permission to apply the patch below to fix the
problem. I tested it by building an i686-pc-linux-gnu toolchain on a
machine with no MPFR libraries installed, but with a copy of the mpfr
3.1.0 sources installed in-tree. I also built a second toolchain with
an in-tree copy of the mpfr 2.4.2 sources, just to make sure that the
old paths still worked. Both builds worked.
OK to apply ?
Cheers
Nick

* configure.ac (mpfr-dir): When using in-tree MPFR sources
allow for the fact that from release v3.1.0 of MPFR the source
files were moved into a src sub-directory.
* configure: Regenerate.
