Yes, Automake should either detect a ".POSIX:" in the Makefile.am file (at least if it is the first non-comment line) and place it at the beginning of Makefile.in, or provide an option to be used with AM_INIT_AUTOMAKE (or AUTOMAKE_OPTIONS) in order to have a ".POSIX:" at the beginning of Makefile.in. > But ... have you tried to run a Makefile originating from Automake with > .POSIX in effect?

So, the ".POSIX:" is necessary for GNU Make in order to detect errors[*] (fortunately, GNU Make does not seem to care about its position in Makefile).
