* glibtop_machine.h, procdata.c, proclist.c, procmap.c, procmem.c,
procsignal.c, procstate.c, procuid.c, open.c, mem.c: Initial
Solaris 2.5 port. It's far from being complete and hasn't been
tested properly. We'll need setuid root daemon, which is
currently not implemented. #ifdef symbols to check are
HAVE_PROCFS_H and KSTAT_DATA_UINT32. These will be defined on
Solaris 2.6 and later, but not on earlier releases.
