Subject: Don't rely on POSIX-conformant comment parsing.

POSIX.1-2008 specifies that comments in makefile syntax start with a "#"
and continue "until an **unescaped** <newline> is reached" (empahsis
added).

FreeBSD's pmake apparently ignores the backslash before the newline in
comments and prints a "Need an operator" error message while parsing a
generated src/Makefile:

    $ make
    Making executable files...
    "Makefile", line 49: Need an operator
    make: fatal errors encountered -- cannot continue

NetBSD's pmake on the other hand appears to be POSIX-conformant in this
regard.
