Sandbox branch for gfortran 4.5 patches

[Jerry DeLisle]

On IRC today Steve Kargl suggested that maybe we need a dedicated branch for 4.5 
patches.

This would allow us to commit patches and continue working with up-to-date svn 
status while we wait for 4.5 branch to happen, then we can merge back right 
after that. I know i have a number of patches backed up, waiting.

This would allow us to get Janne's I/O patch, Daniels I/O patch, and my I/O 
patches put together as well a a few Front-end things I am aware of.

If everyone concurs, who wants to set it up.  Maybe call it "gfortran-devel"

Regards,

Jerry
