[Bug bootstrap/38014] New: [4.4 regression] in-tree gmp and mpfr libraries no longer work

[ian at airs dot com]

In gcc 4.3, you can unpack the gmp and mpfr libraries into your source tree,
and gcc will build, even if gmp and mpfr are not installed on the host system. 
That appears to be broken in mainline as of 2008-10-22.  The problem is that
the top level configury passes --with-gmp-build when configuring mpfr.  The
mpfr library records that in its Makefile using CPPFLAGS.  Now the top level
Makefile overrides CPPFLAGS.  The effect:

Is something missing from the description?
In-tree gmp and mpfr seems to work for me as of r141574, for cris-elf, on a
Fedora 8 system.
Dunno if it matters that there's also:
mpfr-2.3.0-1.fc8
gmp-4.2.2-4.fc8
gmp-4.2.2-4.fc8
package mpfr-devel is not installed
gmp-devel-4.2.2-4.fc8
gmp-devel-4.2.2-4.fc8

Maybe you configured with a relative configure-path, or is it the nativeness of
your build?
grep exception.c build-log gives

The problem reproduces for me -- for both i686 native 32 bit compiler build and
x86_64 cross compiler build.

hp: It will work if gmp is installed on the system.  The problem is that mpfr
can't find gmp.h.  If gmp is installed, then it can, and everything works.

------- Comment #5 from drow at gcc dot gnu dot org  2008-11-14 15:37 -------
Patches reverted.  This is really a bug in gmp/mpfr/intl, but no point
triggering it.
