8# commands) before the first noncomment line in the makefile, make shall
9# process the makefile as specified by the Posix 1003.2 specification.
10# make(1) sets the special macro %POSIX in this case (to the actual
11# value "1003.2", for what it's worth).
12#
13# The rules below use this macro to distinguish between Posix-compliant
14# and default behaviour.
