All I can say is that I cannot reproduce even the "Error 127" message
with the MinGW build of GNU Make 3.81 beta3.  I get "Error 2", which
is entirely reasonable (it's the Windows code for "file not found").

Because in the first case, Make tries to run the command without
invoking the shell, while in the second case, the quotes present in
the rule's command prevent it from doing so

Make invokes the shell only when it sees special characters in the

Note that only the second test causes the "error 127" thing.  So I
submit that this error code comes from the ported shell that you use
(what port of which shell is that, btw?).  In other words, it's not a
Make issue, it's an issue with your port of sh: it returns 127 when it
fails to run this command.  The shell I use (a port of zsh) returns 1
in that case, which is what I'd expect.
