1.0.4: Mon Mar 3 17:54:47 EST 1997
* port: work around for OSF "memory currupt" - the OSF
rtld was calling malloc() before entering main()
* port: revamp automatic extern generation
as OSF/1 CC choked macro(#ifdef)
* port: change itod() and dtoi() -> nnitod(), nndtoi()
as AIX/HPUX used dtoi() for vnode manipulation
* bugfix: history rebuilding code didn't actually work
due to missing space
* change: smarter locating of cpp for genextern
* bugfix: spelling police
