>How-To-Repeat:
	Cross-build -current for vax on i386.  Install.  Boot.
Attempt to run 'ps -aux'.  Watch it fail.  Determine 'ps -u' doesn't
work.  Try 'top'.  Watch it die too.  Investigate if 'systat pigs'
dies too.  It does.  ('systat iostat' and 'systat vmstat' work just
fine... )
>Fix:
	Please.

    As was noted in the port-vax list, these problems were due to the use of 
 the log() function and the use in log() of finite() which appeared to be
 ignored when using builtins and accessing the invalid floating point 
 value used for NaN.
