Hi Dmitry,

I am satisfied with simply using 

  quote(h,"#include <unistd.h>")

Canlidl does not need to know the value of _SC_NPROCESSORS_ONLN only
that the type is (something like) an enum.

No need for a camlidl bug report but the manual could benefit from an
index of the keywords.

Thanks for you help.
