Pattern rules are not truly portable: they are not defined in the POSIX
standard for example.
If you want a makefile that's portable between many variants of make you
need to use suffix rules:
.SUFFIXES: .in .out
.in.out:
@echo "creating $@ from $<"
Of course, a better way to go is to just require the use of GNU make:
requiring a portable make is infinitely simpler than writing portable
makefiles.
