unsigned os_t

[Tony van der Hoff]

Hi,

I believe os_t, the monotonic time, should be unsigned, not a signed int
as at present.

OSLib practice is that anything on which arithmetic can be performed should
be signed, but I think that in this case the arithmetic is generally to
compare it with a previous time, and this is made a lot harder by it being
signed. I always seem to convert it to unsigned anyway.

If I change it, it will be binary compatible with old code, although anyone
re-linking would have to recompile. 

Can anyone think of a good reason not to change os_t to unsigned?
