Re: Porting CommonC++ on QNX

[Federico Montesino Pouzols]

        Perhaps a symbol definition is needed on QNX in order to
activate POSIX 1003.1b? I would have a look at /usr/include/sched.h to
see what #ifdefs are there around the following line:

/usr/include/sched.h:26: #error POSIX Scheduling needs P1003.1b-1993
