Hi,

what is the meaning of MACHINE and MACHINE_ARCH in bmake?

For NetBSD/i386 MACHINE is i386 (taken from /usr/include/machine/param.h
with cpp) and MACHINE_ARCH is also i386 (determined by "uname -p" in
machine.sh). 
On Solaris/x86 MACHINE is sunos5.i86pc and MACHINE_ARCH is i86pc (both
determined in machine.sh).

Is MACHINE_ARCH supposed to be constant on an operating system across
different machines if they use the same processor family (eg, x86 and
compatibles) ? Solaris seems to do this, as far as I know MACHINE_ARCH
is always "i86pc" (output of "arch" or "uname -m") independant of
specific CPU (Pentium, P II, P III, AMD...) and number of processors.

ciao
