-Q8K- What does it take to get Tcl/Tk to compile on 386bsd/Linux or other Posix/ANSI C systems not already supported?

A8K. Patches for 386BSD were posted to comp.lang.tcl back in Nov. 1992 to
alt.sources.  See one of the ftp archive sites for this group for them.
Basically, there were some setting of defines and a few places where 
const char * had to be used in place of char *.
