There shouldn't be much Cygwin-specifc in these files and they are quite
short.  Please check the Cygwin files against the files from RTEMS.
Maybe it makes sense to use them instead and just add the (minor)
differences to Cygwin.  If the types used have the same size and the
same signedness, there shouldn't be much of a problem anyway.

However, I'd like to defer this by a few days or weeks.  We're just
in the beta phase for Cygwin 3.4, and I would rather have stable
headers for now :}
