The legal status is that FSF *and* Graham has a copyright claim
to the files. The code was originally copyright to FSF and eCos
license. The fact that Graham has a copyright claim to it is unproblematic
for now.

If in the future FSF wants to tinker with the eCos license, then the TSE
becomes a problem, because without Graham's consent(or copyright
assignment), the licensing for his changes can't be changed.

Since the current situation is unproblematic, we can just wait to
see if Graham comes out of the woodwork...

Eventually when nios2ecos is mature enough to be committed to
eCos CVS, then we either ditch the TSE or rewrite it.

(The biggest problem with nios2ecos, IMHO, is that quartus
must be installed to build. This makes it impossible e.g. to put
build tool binaries under version control... I'm not 100% convinced
that uClinux required quartus installed to build...)
