Libguestfs - Aug 2013 - relicense module spawn-pipe

hi,

I would like to use the module spawn-pipe in a library called libguestfs to
make it compileable under mingw. currently the library is using the
fork/exec combination which doesnt compile under mingw (mingw doesnt
support fork). spawn-pipe looks like a good replacement, however it is
licensed GPL which is a problem for an LGPL library.

Is it possible to relicense that module (and its dependencies) to be LGPL
instead ?

Thanks,

Or
