BTW, it would be nice if support for pattern rules were added to BSD make 
because POSIX says more or less the same as the GNU make manual:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/make.html

"Consideration was given to adding metarules to the POSIX make. This would 
make %.o: %.c the same as .c.o:. This is quite useful and available from 
some vendors, but it would cause too many changes to this make to support. 
It would have introduced rule chaining and new substitution rules. However, 
the rules for target names have been set to reserve the '%' and '"' 
characters. These are traditionally used to implement metarules and quoting 
of target names, respectively. Implementors are strongly encouraged to use 
these characters only for these purposes.

A request was made to extend the suffix delimiter character from a <period> 
to any character. The metarules feature in newer makes solves this problem 
in a more general way. This volume of POSIX.1-2017 is staying with the more 
conservative historical definition."
