Om,
Thanks! This fixes make pc. I'm able to compile as well as run
simulations with this. The other programs I had tried out, were using
the same pthread.h as TOSSIM. They are working even with the modified
pthread.h. So it seems that the problem must be with something TinyOS is
doing.
Thanks,
Nupur.
