According to
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/sys/resource.h.html
on implementations where all resource limits are representable in an object of
type rlim_t, RLIM_SAVED_MAX and RLIM_SAVED_CUR need not be distinct from
RLIM_INFINITY.  I think this is the case in djgpp so I have also added
RLIM_SAVED_MAX and RLIM_SAVED_CUR.
If nobody objects I will commit the patch below.

Regards,
Juan M. Guerrero
