René,

Your best bet would be to patch the cygwin source code from cvs and
generate a diff from that.  You can find out more about the process
here:

http://cygwin.com/contrib.html

You'll want to generate the diff and submit it to
cygwin-patches AT cygwin DOT com.  You might also want to provide a testcase
c program to demonstrate why these changes are needed.  Also,
referring to specific standards might help as well.  Note, if you
make less then 10 lines of changes to the cygwin code, you probably
do not need to submit a copyright assignment.

Cheers,
Nicholas
