Thanks Mike.

I still do not get who is to define __USE_XOPEN_EXTENDED macro ?
My compiler does not do it, neider my uClinux Makefile.

Would that say that I have to define it explicitly by changing uClinux
Makefile and passing the defines to copiler line options ?
Similar when I compile apps, I always have to explicitly add -D_XOPEN_SOURCE ?
