This is true.. but I don't see what you're getting at.  The fundamental
problem I encountered is that this (legal) code:

catch ( app_exception ) { }
catch ( some_other_app_exception ) { }

..will be expanded to the following when using the macro in pthread.h:

catch ( Pthread_exception_cancel ) { throw; }
catch ( Pthread_exception_exit ) { throw; }
catch ( app_exception ) { }
catch ( Pthread_exception_cancel ) { throw; }
catch ( Pthread_exception_exit ) { throw; }
catch ( some_other_app_exception ) { }

..and VC++ will not compile that because of the existence of multiple
handlers for Pthread_exception_cancel and Pthread_exception_exit.
