I'm trying to debug a problem with xemacs that involves the child
process forked when you execute M-x shell.
None of the mechanisms in the gdb documentation for choosing to step
into the child process (instead of the parent) after a fork() seem to
work for me. That is, in particular, setting follow-for-mode to child
still leaves me in the parent after stepping over a fork().
Setting detach-on-fork to 'off' also seems to have no effect.
Have I misunderstood something, or does this aspect of gdb just not
work under cygwin (x86_64, 1.7.29-2)?
