I do not know if this issue has already been discused but I have noticed
that the DJGPP port of gcc crashes if it does not find djgpp.env.  If gcc
needs to load djgpp.env and fails, would not it be better that it issues
some kind of error message instead of crashing?
For an user not familiar with DJGPP it would be hard to figure out
what has gone wrong.

The output below is produced by gcc471b on WinXP after having deleted
djgpp.env.
