So, I am cleaning up more autoconf cruft, and one remaining thing
is the OS-specific defines. I don't think anyone will object to
the removal of SCO_5_STDIO specific code, but there is one that is
used a surprising amount: BSD42.
This code has two purposes: if you have a & in the GECOS field, it
substitutes in your login name in to your real name field. Personally I
always found this feature a bit dubious, and from my experience not much
supports that. I propose we just junk this support.
The other use of BSD42 seems to be in msh.c; basically, if we get
interrupted in a signal, longjmp() out of the signal handler back
to the main command loop. I guess this code was before signals
interrupted system calls? Anyway, I am thinking that this can be
junked as well. Any objections?
(Okay, for purists; BSD42 also controls the use of the MIME content
cache, for reasons I do not pretend to understand).
