There's certainly a chance :-)

Cygnus has had such a feature in our compilers for a while to satisfy
some customer needs.

That change was submitted to gcc2 and rejected.  There's some interesting
issues that need to be resolved before we could integrate our patch.

THe most important issue would be bug reports.

We already have a tough time getting all the information we need to
reproduce & fix problems.  Adding an environment variable of this
nature just makes things harder since someone could put options in
the environment variable, then forgot to tell us about them when
they report a bug.

I believe this was the primary objection to including such an option
in gcc2.
