DCL isn't involved, here. For make for VMS, a DCL symbol 'echo' defined
as '"write sys$output """' is not the same as using 'write sys$$output
"' in the action.

At the time just prior to run the action routine(s), I think it is in
child_execute_job, in the first case there is no VMS style quoted
string: make for VMS will interpret redirection introducers. In the
second case there is a VMS style quoted string (no matter whether it is
correctly terminated or not be): make for VMS will not interpret
anything within such strings.

For Unix, the single quotes were used to avoid shell variable expansion.
For VMS and echo defined by a DCL symbol, replacing single with double
quotes seems to be sufficient. Even for your GNV echo command, as there
is no shell involved.
