Hi Stephen.
All suggestions implemented now, thanks.
Cheers

| The seems reasonable to me if you ever need to have just one of the
| libraries. If you put the .sig and .sml in a .cm file and always
| refer to that, MLton, just as CM, will make sure that the code only
| occurs once in the program.

|
| Done.
|
|
| I have a few minor tweaks for Makefile, and one for spin_cube.sml.
|
| Regarding the Makefile, wouldn't it make more sense to pass GL_c.o and
| GLUT_c.o to each call to mlton instead of using GL_c.c and GLUT_c.c?
|
| You have a lot of calls to "mlton" that should be to $(mlton).
|
| To keep CVS quiet, I've found it nice to put all the stuff that you
| currently have in your clean target into the .cvsignore, and then have
| make clean use that file. That way all the information about what's
| junk is in once place. You can have the clean target call our
| bin/clean script, which is what we do in most of our other Makefiles.
|
| Finally, I need to request a change to spin_cube.sml. There need to
| be type annotations (: Real32.real list) on the declarations of
| whiteLight, sourceLight, and lightPos. The latest MLton will actually
| report an error if you don't have them. The reason is that the new
| (correct) handling of topdecs resolves overloading of constants on
| those declarations before looking at the uses of whiteLight, etc,
| which means that it resolves them as "real list", not "Real32.real
| list". So, the change is
|
| val whiteLight: Real32.real list = [0.5, 0.5, 0.5, 1.0]
| val sourceLight: Real32.real list = [0.8, 0.8, 0.8, 1.0]
| val lightPos: Real32.real list = [0.0, 0.0, 0.0, 1.0]
|
| Another alternative would be to make sure there are no semicolons
| (like the one on line 9) that cause the program to be split into
| topdecs, although I'd prefer the annotations, which would be more
| robust (and informative).
