It was submitted: 
<http://gcc.gnu.org/ml/gcc-patches/2002-08/msg00354.html> and there is
support for multiple entry points according to Mark Mitchel in one of 
the follow ups:

Note that Zack recently checked in better support for alternate entry

will save even more space that your approach, and be faster as well.
