okay, so these are the options:

1) forget redhat and forget them ever being helpful and supporting
strategically important free software projects, and go back to using
dcethreads posix draft 4 "emulation".

2) forget redhat and forget them ever being helpful and supporting
strategically important free software projects, and put the cancellation
"wrapper" side back into the dcethreads library - just keep the same
posix "final draft" API.

lord only knows what would happen on pthreads-win32 when compiling
freedce with mingw32, with the "wrapper" stuff back in, but i'd be
fascinated to find out.

3) think of ways to persuade the developers of glibc to enter into
reasonable conversations and dialog to help support a strategically
important free software project.  how does any other project manage
this (and what in hell's name prompted ulrich to be so dismissive?)
