    _______________________________________________________

Details:

Given the following Makefile:

all:
        @echo "You shouldn't be seeing this." &> /dev/null

GNU Make 3.80 has the expected behavior, which is to redirect stdout/stderr
to /dev/null .

3.81, 3.82, and CVS do not redirect either stdout or stderr.  Instead, the
echo command is backgrounded, and the output appears in the terminal.

If I replace &> with >& (which also works in GNU Make 3.80):

all:
        @echo "You shouldn't be seeing this." >& /dev/null

I get the following error message:

/bin/sh: Syntax error: Bad fd number
make: *** [all] Error 2

Here is a workaround for redirecting stdout/stderr that does work in GNU Make
3.81 and up:

all:
        @(echo "You shouldn't be seeing this." 2>&1) > /dev/null
