            Bug ID: 58238
           Summary: cc1 crashes when built for ms-dos cross-compiling
           Product: gcc
           Version: 4.7.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mikulas at artax dot karlin.mff.cuni.cz
              Host: x86_64-unknown-linux-gnu
            Target: i586-pc-msdosdjgpp
             Build: x86_64-unknown-linux-gnu

Configure gcc-4.7.3 with these options:
../gcc-4.7.3/configure                   \
        --prefix=/usr/local/gcc-4.7.3/   \
        --enable-languages=c             \
        --target=i586-pc-msdosdjgpp

Run make.
You get a gcc/cc1 executable that always crashes.

If you look at i586-pc-msdosdjgpp/libgcc/config.log, there is:
configure:3584: /usr/src/gcc-4.7.3-build/./gcc/xgcc

Please try the attached patch.  I tested it with a simple "#include stdint.h"
but we made the type names exact matches (way back when) for a reason...
