If the code has been assigned to the FSF and is now owned by the FSF, we
can't use it. IANAL.

Red Hat has special licensing considerations which I mentioned in the
URL that I provided. The LGPL still requires that source code be
distributed if you are *providing the library* does it not? If I try to
sell you a copy of glibc, I will have to provide you with the sources.
If I sell you a copy of a program linked with glibc, I don't have to
give you the sources for glibc. It's a subtle distinction, but this is
why we can't use it.
We occasionally sell copies of the cygwin license for proprietary use.
You can scream or be offended by this fact but it is a fact of life.
That means that we have to own what goes into newlib/cygwin or the
licenses of the source has to allow distribution of binaries without
source code so that cygwin1.dll is encumbered.
IMO, the LGPL does not allow this. IANAL.
At any rate, cygwin is about six years old now. This issue has been
endlessly hashed and rehashed, as you may imagine.
As to whether the author of the code can reassign the code for use
in cygwin, that is another issue. I don't know if John's statement
(quoted from another message) is adequate or not:

IANAL. And, more importantly, I don't control what goes into newlib. So,
assigning the rights to me will not be useful.
I again suggest that you take this discussion to the newlib mailing
