[PATCH] Fix PR55784

[PATCH] Fix PR55784

[Richard Biener]

This supposedly fixes PR55784 according to people running into the
issue.  We need to add GMPINC to the include paths everywhere as
we now include gmp.h from system.h.

Bootstrap and regtest running on x86_64-unknown-linux-gnu.

Ada bits approved by Eric in bugzilla.

Richard.

2013-01-02  Richard Biener  <rguenther@suse.de>

	PR bootstrap/55784
	* configure.ac: Add $GMPINC to CFLAGS/CXXFLAGS.
	* configure: Regenerate.

	ada/
	* gcc-interface/Makefile.in: Add $(GMPINC) to includes.
