           Summary: [4.6] gcj spec files references incorrectly crtmt.o on
                    i686-w64-mingw32 target
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: blakawk@gentooist.com


When cross compiling GCJ with host platform i386-redhat-linux and target
platform i686-w64-mingw32, the GCJ spec file is generated adding crtmt.o to
startfile. The path to this file is not a full path, so it is looked up in the
current directory, resulting in No such file or directory error when compiling
a .exe with GCJ.

Versions used are the following:
# i686-w64-mingw32-gcj -v
Using built-in specs.
Reading specs from
/home/users_csee/parizet/mingw32/root/bin/../lib/gcc/i686-w64-mingw32/4.6.1/../../../../i686-w64-mingw32/lib/libgcj.spec
rename spec startfile to startfileorig
rename spec lib to liborig

gcc version 4.6.1 20110401 (prerelease) (GCC)

and mingw32 revision 4105 from the trunk.

When removing the crtmt.o from startfile in libgcj.spec file, it works fine.
