             Bug #: 56276
           Summary: libgcc_*.dll is installed to wrong directory during
                    build
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: karlson2k@gmail.com
              Host: i686-pc-mingw32
            Target: i686-pc-mingw32, i686-w64-mingw32, x86_64-w64-mingw32
             Build: i686-pc-mingw32

When building all (by 'make all) or building libgcc by 'make
all-target-libgcc', the following commands are executed:

# Now that we have built all the objects, we need to copy
# them back to the GCC directory.  Too many things (other
# in-tree libraries, and DejaGNU) know about the layout
# of the build tree, for now.
make install-leaf DESTDIR=../.././gcc \
          slibdir= libsubdir= MULTIOSDIR=.
make[2]: Entering directory
`/home/xxx/mingw-w64/packages/gcc/build/4.7.2-i686-w64-mingw32/i686-w64-mingw32/libgcc'
/bin/sh ../../../../source/gcc-4.7.2/libgcc/../mkinstalldirs ../.././gcc
/bin/install -c -m 644 libgcc_eh.a ../.././gcc/
chmod 644 ../.././gcc/libgcc_eh.a
/home/xxx/mingw-w64/packages/gcc/build/4.7.2-i686-w64-mingw32/./binutils/ranlib

../.././gcc/home/xxx/mingw-w64/mingw-w64-i686/i686-w64-mingw32/lib/../lib
../.././gcc; /bin/install -c ./shlib/libgcc_s_dw2-1.dll
../.././gcc/home/xxx/mingw-w64/mingw-w64-i686/i686-w64-mingw32/lib/../lib/libgcc_s_dw2-1.dll;
/bin/install -c -m 644 ./shlib/libgcc_s.a ../.././gcc/libgcc_s.a


As result, unwanted directory
'../../gcc/home/xxx/mingw-w64/mingw-w64-i686/i686-w64-mingw32/lib/' is created.
I'm sure that 'gcc' directory shouldn't have any 'home' subdirectory. 
'libgcc_s_dw2-1.dll' is placed to
'../../gcc/home/xxx/mingw-w64/mingw-w64-i686/i686-w64-mingw32/lib/' (relative
to libgcc build directory).

--- Comment #1 from Kai Tietz <ktietz at gcc dot gnu.org> ---
Due the fact that your target-triplet is different to the build-triplet (and
the host one) gcc assumes correctly that you are doing a cross-compilation. 
Therefore installation-directory of <target>/lib is intended.
