             Bug #: 50156
           Summary: in-tree CLooG is not picked up by toplevel configure
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: vanboxem.ru...@gmail.com

gcc/config.log

With the patches attached to 

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50139

I can successfully build GCC with in-tree GMP/MPFR/MPC/PPL/CLOOG for

--host=x86_64-linux-gnu --target=*-w64-mingw32 --build=x86_64-linux-gnu
--host=*-w64-mingw32 --target=*-w64-mingw32 --build=x86_64-linux-gnu

I can see in the build logs all libs are built in tree, but when linking the
cc1 executable, the cloog libs are missing. Searching for the "no-graphite"
error message ("sorry, unimplemented...") I found that HAVE_cloog is not
properly defined, which is a symptom of clooglibs not being properly filled in
in gcc/configure

Attached is gcc/config.log
