The exception is made when the library has a competitive equivalent,
such that the intrinsic value of the library itself isn't enough for
users to warrant using it.  For example, the C library is LGPL because
there are lots of C libraries, but realine is GPL because there are no
equivalents.

The terms of the LGPL aren't the problem.  It's the *copyright* that's
the problem.  Any code in cygwin or newlib must be owned by Red Hat,
or distributed under terms that allow Red Hat to distribute it the way
it does (combination gpl and proprietary).  The GPL and LGPL simply
don't give us the option of offering a proprietary-use license, and
such licenses fund a lot of the official work on those projects.  We
would need a legal exception to use someone else's [L]GPL'd work.

The files in that directory claim to be owned by the FSF.  Thus, you
aren't legally allowed to grant exceptions to the LGPL for them.  The
test/* files claim to be owned by Stephen Moshier.  Exceptions for
those would have to come from him.

Yes, I'm being picky, but lack of attention to such details is what
legal nightmares are made of.

Permission would have to be granted to Red Hat, and they'd probably
want something on paper with a signature.  They'd probably also want
something from your employer, to make sure what you did isn't a
work-for-hire (which you also wouldn't own).  As you are a math
professor at a university, it is likely that they, not you, own any
such work you do there.
