Subject: bug#36296: 26.2; cannot-suspend value on MS Win & resume description
Date: Wed, 19 Jun 2019 19:50:48 +0200

Hello,

on MS Windows (official build) variable `cannot-suspend' has value
`nil', while according to this thread on help-gnu-emacs:
https://lists.gnu.org/archive/html/help-gnu-emacs/2019-0/msg00259.html
probably should have value `t'.  Although there is a line in
documentation of suspend-emacs ``If `cannot-suspend' is non-nil, or if
the system doesn't support job control, run a subshell instead.'', so
it suppose to work even with `nil' and it does for me (both 26.2 and
emacs-27.0.50-snapshot-2019-06-08-i686), but as Ó. Fuentes wrote in
the thread above:

So maybe set it to `t' for MS Windows to be sure it'll work?


And the second part, as I wrote in mentioned thread:
