Yes.  I did a google search now for "Catch of fork not yet implemented"
and found this:

That'd be great!

Right, that's old PR8595 - environ.exp could run on more platforms:

Right.  I think most is_remote checks are wrong.  This is really
a protocol limitation, a bit orthogonal to protocol used or whether
the host and target machines are the same.   Probably the right
check is:

  [target_info gdb_protocol] == "remote" || [target_info gdb_protocol] == "extended-remote"

Better yet, add a new supports_target_env or some such to lib/gdb.exp
that encapsulates this.

That's fine.  It waited over 12 years already, it can wait a
little while longer.  :-)
