Hi Evan,

I'd prefer to stick to the existing makefile. It might be scary to
say that it depends on GNU make but bear in mind that of all the make
implementations I've tried only OpenBSD make had some trouble with it.

I think sticking to GNU make will work fine for us. We are not crazy
enough to start using the insane features that it does provide but something
along the lines of

        $(BIN): $(LIB)

is sane enough even if it does not work everywhere. This is really the
only problem we've had so far.

I do not want to start another sh vs makefile thread. It is fair to say
that there exists a make implementation that is more intuitive than using
a shell script to build a set of programs and libraries.
