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