Better solutions than what you found are:

  o Invoke g++-3, gcc-3, g++-4, or gcc-4 directly.  These are executables
    and work fine from the command prompt.
  o Create g++.bat and gcc.bat that call your preferred executable.

These are better options than the one you found because they protect the
integrity and structure of the package.  Upgrades will not have leftover
".bak" files from earlier versions and so on.  Also, your approach interferes
with the use of 'alternatives' to select the compiler version you want.  This
is made convenient by 2 scripts, and
This mechanism is the reason that gcc, g++, gcj, and gnat are symbolic links
now rather than executables.
