FFe: Sync gcc-mingw-w64 5 (universe) from Debian unstable (main)

Please sync gcc-mingw-w64 5 (universe) from Debian unstable (main)

Explanation of FeatureFreeze exception:
gcc-mingw32 FTBFS, it's been removed from Debian and superseded by this package, which we already have, this version takes over the gcc-mingw32 as a transitional package and builds with gcc-4.6 and gnat-4.6
This will allow us to remove gcc-mingw32 without a second thought
Only reverse dependency is mingw-w64 which appears to build with the new packages and this source is unseeded

Changelog entries since current precise version 2:

gcc-mingw-w64 (5) unstable; urgency=low

  * Add the DMUA flag set by Didier Raboud to the control.source file.
  * Add a warning to the generated debian/control file indicating that
    it shouldn't be modified directly.
  * Fix the version for Breaks/Replaces at 4.6.3-3+4, since this is the
    earliest version of the post-split package in the archive. Fixing
    the version avoids making the package set uninstallable.

gcc-mingw-w64 (4) unstable; urgency=low

  [ Stephen Kitt ]
  * Split package into gcc, g++, gfortran and gnat packages.
  * Enable the Objective-C and Objective-C++ compilers.
  * Split package into 32- and 64-bit specific versions (-i686 and
    -x86-64) - see thread starting at
    http://<email address hidden> for rationale.
  * Build with gcc-4.6 explicitly, at least until gnat-4.7 is available
    (Closes: #667173).
  * Standards-Version 3.9.3, no change required.
  * Provide a transitional gcc-mingw32 package for backwards-
    compatibility (Closes: #644769); in addition, with regards to bugs
    filed against gcc-mingw32:
    - gcc-mingw-w64's version of mm_malloc.h is correct (Closes: #651300);
    - gcc-mingw-w64 compiles programs (Closes: #658619);
    - gcc-mingw-w64 provides shared versions of libgcc and libstdc++
      (Closes: #540783);
    - the packages' dependency structure ensures that the various compiler
      packages depend on the appropriate development packages (Closes:
      #567698).
  * Update debian/copyright using the version provided by gcc-4.6.

  [ Didier Raboud ]
  * Confidently set the DM-Upload-Allowed flag to yes.

gcc-mingw-w64 (3) unstable; urgency=low

  * Disable Ada support on armhf and hurd-i386 for now, based on a patch
    by Peter Green (Closes: #658526).
  * Wrap-and-sort debian/control.full.
  * Check before moving libraries, when bootstrapping there is nothing
    to move.
  * Update debian/control.bootstrap with changes made to
    debian/control.full.
  * Add spelling fix for "writting".
