With GCC all is possible. :-)

The solution to running multiple versions:

Install WinAVR to the directory that you want.
In my case G:\WinAVR345 and G:\WinAVR411, for
the respective versions.  IT department doesn't want stuff
installed on C:\ in my case.  Then Delete the registry keys (and reboot),  
so there
is no confusion between 4.x.x vs 3.x.x et.al.

Then use the 'Junction' program from here:

http://www.microsoft.com/technet/sysinternals/FileAndDisk/Junction.mspx

to make a virtual C:\WinAVR symbolic link via:

junction -s C:\WinAVR G:\WinAVR345

which should then result in:

Created: C:\WinAVR
Targetted at: G:\WinAVR345

Example batch files:

setup345.bat:
PATH=G:\WinAVR345\BIN;\WinAVR345\UTILS\BIN;%PATH%
junction -s C:\WinAVR G:\WinAVR345

setup411.bat:
PATH=G:\WinAVR411\BIN;G:\WinAVR411\UTILS\BIN;%PATH%
junction -s C:\WinAVR G:\WinAVR411
