           Summary: [4.7 Regression]: build fails on crtstuff.c / crtbegin
                    using default CRT_CALL_STATIC_FUNCTION
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P3
         Component: regression
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hp@gcc.gnu.org
                CC: rth@gcc.gnu.org
              Host: x86_64-unknown-linux-gnu
            Target: cris-axis-elf


A patch in the revision range last known working 176012, first known failing
r176032, caused the build for cris-elf to fail as described in bug 49680 (first
quote). After the immediate problem is fixed there's a second problem which
seems to be that the default definition of CRT_CALL_STATIC_FUNCTION doesn't
work anymore (messages also quoted in bug 49680), due to a change in the
mentioned range.

A documentation patch is suggested as a general fix.  An alternative would be
to provide a better default definition of CRT_CALL_STATIC_FUNCTION.
