No I/O redirection under GDB

- Authentication-results: sourceware.org; auth=none
I just found that gdb's "run" command doesn't action redirection (e.g. run
</dev/pty2 >/dev/pty2 2>&1, where the shell on /dev/pty2 is doing a long sleep).
Instead, the invoked program gets the redirections as command line arguments.
Looking through the archives, I found
https://sourceware.org/ml/cygwin/1999-04/msg00355.html documenting this
behaviour. Chris Faylor commented at the time that fixing it was more trouble
than it appeared.
That was 15 years ago - has anything changed since? Anyone up for this or should
I have a go? I *could* simply make my target do the redirection itself, but that
doesn't help anyone else. OTOH if changing gdb really *is* that hard, maybe I
should just change my program anyway.
Any advice welcomed,
Cheers ... Duncan.
