IANAL, but i can't see why not. As far as i understand, you can
incorporate public domain code to whichever project you want,
retaining a copyright, and then distribute everything under cygwin, or
commercial or whatever license.
Doug Lea's malloc() is in public domain, for instance. And IIRC it's
now used by cygwin as a default malloc routine.

Why? It's obvious for mingw people to implement, say, openssl library
as a dll. It exports several data items. Mingw version of ssl.dll
would export them. Now, imagine that someone writes an application
which uses data items exported from ssl.dll and compiles in with
mingw. If _pei386_runtime_relocator is linked within application and
called at startup, then all references from foo.exe to ssl.dll which
have to be fixed up, will be.
The core idea of _pei386_runtime_relocator() is to be generic, as long
as PE on i386 is concerned, hence the name. For instance, i don't see
much difficulties for interix to use it too.
