You can easily version control environment variables, if you just keep
them local to your makefile / commands.

You don't have to change your PATH systemwide to do a simple build.

PATH=/path/to/special/gnat gnatmake stuff

Put that in your makefile, and you now have a version controlled PATH.

If you're worried about compiler versions, simply check for that in the
makefile and break out if there's a version mismatch. This is exactly
what proper build scripts are for. If Bob screws up then he will be
notified and it's then up to him to fix his own system. Create a
makefile.conf and have something like GNATMAKE_VERSION=4.8.2 and check
for that.

And just to be clear: I'm not advocating against gprbuild or gpr files,
I'm merely pointing out that a well-written makefile would solve Joe
and Bob's PATH/compiler woes. :o)
