This is unnecessary under Linux. Binaries will use the appropriate shared
library automatically, and for statically linked programs this is irrelevant. All
setver really does under DOS anyway is permit programs that want a specific
version of DOS to run, when they would otherwise fail despite being compatible.
The only programs for which this was true, generally, was the utilities that came
with DOS. AFAIK, setver did nothing but change which version DOS would report to
given programs.

I don't know if one of the development guru's on this thread already
mentioned this, but:

How about something that functions like M$-DOG's setver.exe (maybe call
it setlib?) so that if you have a binary that was compiled using a
specific libc/x,whatever, you could have the executing process use that
library instead of the most current one?

Sorry, I wasn't thinking about working around buggy programs. Still, as a general
rule, you shouldn't need to work around a program that references memory after
free()ing it. The program should get fixed. Unfortunately, Netscape sucks and
they don't ship source.
