SPARC boxes, and PCs running Linux, FreeBSD, NetBSD, or Solaris are
all fully supported. Win32 and HP boxes are in pretty good shape.
DEC Alphas running OSF/1, Linux or some BSD variant, MIPS and AIX
boxes will need some minimal porting effort before they work (as of
4.06). <Xref LinkEnd="sec-port-info"> gives the full run-down on
