The link options link with -lgmpxx, but do not include the required -lstdc++
and -lm options to make that link successful. This works accidentally if gmp
is built as a shared library, which knows its dependencies at runtime, but if
it is built static, the links fail with a sea of errors about undefined
symbols.
Reprodce by:
configure gmp library with --disable-shared and install /some/where
configure gcc with --with-gmp=/some/where
make bootstrap

>From http://gcc.gnu.org/install/configure.html :
--with-host-libstdcxx=linker-args
If you are linking with a static copy of PPL, you can use this option to
specify how the linker should find the standard C++ library used internally by
PPL. Typical values of linker-args might be `-lstdc++' or
`-Wl,-Bstatic,-lstdc++,-Bdynamic -lm'. If you are linking with a shared copy of
PPL, you probably do not need this option; shared library dependencies will
cause the linker to search for the standard C++ library automatically.

Created an attachment (id=21271)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=21271&action=view)
patch to configure.ac to include needed libraries for static libgmpxx
This is a pretty straightforward fix..

So if we prefer a nonstandard configure option to having it work for the right
reasons, that's okay, I guess...
