[Bug bootstrap/44512] --enable-build-with-cxx bootstrap fails in revision 160669

------- Comment #2 from amylaar at gcc dot gnu dot org  2010-06-13 12:04 -------
When I add a cast to the offending line in c-cppbuiltin.c, the bootstrap
shows another failure:

That was presumably introduced in revision 160582:

2010-06-10  Richard Sandiford  <rdsandiford@googlemail.com>

        * doc/md.texi: Document the "unspec" and "unspecv" enum names.
        * Makefile.in (OBJS-common): Include insn-enums.o.
        (insn-enums.o): New rule.
        (simple_generated_c): Add insn-enums.c.
        (build/genenums.o): New rule.
        (genprogmd): Add "enums".
        * genconstants.c (print_enum_type): Declare a C string array
        for each enum.
        * genenums.c: New file.
        * print-rtl.c (print_rtx): If defined, use the "unspecv" enum
        for UNSPEC_VOLATILE.  If defined, use the "unspec" enum for both
        UNSPEC and (as a fallback) for UNSPEC_VOLATILE.
