Here is output..

So, gnulib's sched.h has provided a definition of 'struct sched_param'
although one is present in EMX U:/USR/include/spawn.h.

What version of EMX is this, and where to download it? I have EMX 0.9d,
and it does not have a spawn.h include file.

Hi Bruno,
Os/2 latest emx is 0.9d
I download the Gcc package from Bird several years ago and there where this Spawn.h included
I attach it...
