6# If the special target .POSIX appears (without prerequisites or
7# commands) before the first noncomment line in the makefile, make shall
8# process the makefile as specified by the Posix 1003.2 specification.
9# make(1) sets the special macro %POSIX in this case (to the actual
10# value "1003.2", for what it's worth).
11#
12# The rules below use this macro to distinguish between Posix-compliant
13# and default behaviour.
