           Summary: reload problem when building winsup
           Product: gcc
           Version: tree-ssa
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: green at redhat dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-cygwin32

Discovered while building tree-ssa cygwin cross with tree-ssa Linux native
compiler.  However, it is also reproducable with the native tree-ssa Linux
compiler directly.

I'll upload the .i file causing the problem.
