Thanks for reviewing.  I'll push the patch in a minute.  I still
think we should rename the struct members as well, though.  There's
no good reason that we have a user of these structures outside
newlib/Cygwin.  But still, *iff* this file is included for whatever
dubious purpose, it might result in problems.

We have two ways to fix this:

- Either guard the definitions additionally with a preprocessor
  expression like this:

  #if defined (__INSIDE_CYGWIN__) || defined (_COMPILING_NEWLIB)
  [...]
  #endif

- or fix the names of the struct members and the newlib/Cygwin code
  using them.


Thoughts?  Jeff?
