The msp430-gcc package is:

* Derived from the official GNU gcc-3.2.3.tar.gz available on any
  GNU mirror, such as http://mirrors.dotsrc.org/gnu/gcc/gcc-3.2.3.tar.gz.

* Includes patches from mspgcc.sf.net.  mspgcc.sf.net maintains much of its
  changes to the gcc as a sparse tree for each version.  The dpatch patch named
  debian/patches/002-mspgcc-3.2.3-20080819.dpatch contains the modifications
  to standard gcc-3.2.3 as a result of applying the mspgcc sparse tree from
  their CVS checked out at date 2008-08-19.  mspgcc CVS is available via
  pserver at anonymous@mspgcc.cvs.sourceforge.net:/cvsroot/mspgcc in the
  gcc-3.3 module.  Yes, the gcc-3.3 module is actually for gcc-3.2.x.

* The dpatch patch named
  debian/patches/003-mspgcc-3.2.3-20080819-FUNCTION.dpatch contains the patch
  also provided in mspgcc.sf.net in the packaging module in patches/.
