libccrt0 has to live in the .exe, not the dll.  If Cygnus had published
an interface specification for cygwin.dll then of course you could
just say that you were following the spec if you provided your own
version, but they haven't.  As I said, I don't know how copyright
law applies to reverse engineering.

Distributing a modified cygwin.dll or putting it at an ftp site
separately from that which depends on it is really pushing things, and
seems pretty dangerous if anyone actually brought suit.

Huh?  The copyright on libcygwin.a and cygwin.dll belong to Cygnus
Solutions, not the FSF; the FSF just publishes the text of copyright,
but that doesn't give them any legal standing.  And it's the courts that
enforce these things.
