OBJDIR = OBJDIR or d.."obj/"

        afile {
                ASBUILDFLAGS = ASBUILDFLAGS or "-mregnames",

The ASBUILDFLAGS are working, but the CBUILDFLAGS aren't located properly,
I think, as the code isn't statically linking the libc library.

I did modify the c.pm file in a few places:

CCOMPILER = CCOMPILER or "cc"


ASCOMPILER = ASCOMPILER or "as"
AS = "%ASCOMPILER% %ASBUILDFLAGS% -o %out% %in%"

afile = simple_with_clike_dependencies {
        class = "afile",
        command = {"%AS%"},
        outputs = {"%U%-%I%.o"},
}

I added the choice of compilers because I think it is important to be able
to have that choice.

Overall I found this to be pretty straightforward, since the work is done
through inheritence and it's just a matter of describing the objects in the
pmfiles.  I am going to work on the original project I've been wrestling
with and I'll post something when I get it completely contained by pm.  I
really appreciate how clear the error messages were.  The above pmfile
could still be tweaked to do individual component building and then build
the program through the group object, instead of having it all in a single
cprogram, although I haven't gone through that yet.

(Gee, any thoughts of a Makefile->pmfile converter?)

thanks!
