Is there a chance to get this trivial fix backported to 4.4 and 4.3, too?

FYI, the problem has been handled in the MPFR trunk r7291 for MPFR 3.1.0.
MPFR's configure script now retrieves the location of the GMP source from GMP's
Makefile and adds the necessary -I... flags to CPPFLAGS.

Note also that the behavior will be different from the one with MPFR 2.x. A
side effect is that library versioning is not supported in this case (by that,
I mean that a GMP upgrade without recompiling MPFR against the new GMP version
may break things) because providing --with-gmp-build makes the MPFR build use
GMP's internals, which may change without notice.

Yep, but I'm on holiday so no hurry. :)

Sorry, no commit rights. I wrote the patch because it was a one-liner, but I
still don't even have a copyright assignment on file.

Can you handle the rest?

------- Comment #9 from marc dot glisse at normalesup dot org  2010-07-13 14:26 -------
Ok, the 4 tests worked fine. I tested with gcc-4.5.0 because the snapshots
complained about the number of arguments to ggc_alloc_cleared_lang_type
(without any patch). I used --without-ppl (otherwise you get gmp through it).
MPC was in-tree for all tests for the same reason.

ldd on cc1 never showed mpfr, and only showed libgmp.so.3 when it was out of
tree. strings on cc1 also confirmed that the right one was used (the system
versions of gmp and mpfr are different from the one I tested in-tree).

The versions of mpfr I tested are the latest (3.0.0) and the oldest on which
configure only warns and doesn't fail (2.3.1).

Yes, C-only bootstrap is enough.

Regarding the removal of an installed GMP, in theory yes, it would be
preferable.  In practice removing it would force you to use an old bootstrap
GCC that does not use MPC/MPFR/GMP, and there is an easy way to check that the
right library is used for the build, so it is not necessary.  Since in-tree
GMP/MPFR are statically linked, just do "ldd *gcc/cc1" in the build directory,
and check that it doesn't include any relevant GMP/MPFR/MPC shared library.

For smoke testing, just compile a simple "int main() {}" file.

Is it enough to test with --enable-languages=c? What is a smoke test, gcc -v?
Does it matter if the system has gmp and mpfr installed, even when doing the
in-tree tests (I hope not, because I won't remove them)?

The patch is okay, but it should be tested with bootstrap, `make install' and a
smoke test after install with:

- in-tree GMP, in-tree MPFR 2.3
- in-tree GMP, in-tree MPFR 3.0
- out-of-tree GMP, in-tree MPFR 2.3
- out-of-tree GMP, in-tree MPFR 3.0

Trivial patch

There doesn't seem to be much point using --with-gmp-build (it is mostly useful
to improve performance a bit, but gcc explicitly tells GMP to be slow), so
let's just use the same options as MPC. It works with mpfr 2.3.1 and 3.0.0. Any
particular trap I am missing?

------- Comment #1 from Denis dot Excoffier at airbus dot com  2010-06-11 08:05 -------
The same applies to mpfr-3.0.0 (now official). The MPFR people have however
added the following note in ./INSTALL:

> As gmp-impl.h and longlong.h are only in the GMP source directory,
> you first need to copy these files to the build directory if it is
> different (there may be other workarounds, such as setting $CPPFLAGS
> to search the GMP source directory).

This may be a better workaround than the one i proposed first.
