[gccsdk] Sys$ReturnCode (was: Parsing wget output)

Ah - I've just discovered that it *will* set Sys$ReturnCode to
zero/nonzero. So with a bit more tweaking, it should be possible to
change MBBack to use that.

However, I did discover that the value of this variable is very
volatile. How safe is it to read? I'm planning on calling wget in a
TaskWindow with Wimp_StartTask, and examining the return code once I get
the TaskCloseDown Wimp message. Is it possible that some other task may
alter its value between wget quitting and MBBack learning of it,
assuming that I am not the only program calling Wimp_Poll in the
desktop?

An alternative solution would be to write a wrapper Obey file and
Wimp_StartTask that, but I'd rather avoid that.
