Patch installed for physmem.c irix6 support


I pulled in the upstream copy of physmem.c, it adds irix6 support and
a DEBUG main function.  (The latter simply keeps us more consistent
with the *utils version.)

Tested on irix6.2 and irix6.5 and installed on trunk and 3.3.



2003-02-21  Kaveh R. Ghazi  <ghazi at caip dot rutgers dot edu>

	* configure.in: Check for sys/sysmp.h and sysmp.
	* physmem.c: Pull upstream copy, add support for irix6.

	* config.in, configure: Regenerated.
