c++.beta - optimization flag -o -> -O

I suggest change the optimization flag from the lowercase 'o' to uppercase 'O'
so there is no conflict with -o option which set the name of the output file. It
could be like this:

-O+[all | space | speed | time ] and other flags

This is not necessary, but it would be nice to have it.
-O0 or -O- -> disable optimization
-O1 -> optimize for size
-O2 -> optimize for speed
-O3 -> all optimization


So,
dmc test.cpp -o test.abc
will compile test.cpp to test.abc and not compile both test.cpp and test.abc
with optimization

By the way, I have saw this on the documentation for dmc.exe switches:
-o SPP only: send result to stdout

what is SPP?

Regards,
Nicky.

SPP is the standalone preprocessor.
