But before we can roll out this compiler, we need to have some written
statement from FSF that says it's legally safe to link with these
libraries even with those problematic files. Who should I contact for
such a statement?
Your attorney. The FSF would have absolutely no reason to issue such
a statement and would not do so. It is not in the business of
offering a legal opinion, especially to a party that wants to build
proprietary software, a concept which they oppose.
The company you obtain support from (surely you aren't using unsupported
software for commercial purposes) may be able to issue you such a statement,
but their indemnification may not be of value to you if you have deeper
pockets than they do.
