I don't think (a) is possible, unless we decide that the option is
only for when MSYS Bash is being used as the shell, and we teach Make
to detect that flavor of Bash.  If we do that, other users who just
might need this mode of operation will not have any fire escapes.  And
if we don't want this only for MSYS, then I don't even know how to
define the conditions under which this option will be needed.
