c++ flags

[cujo]

is it possible to somehow embed optimization levels in c++ source code? i want to compile a program of mine with the -O3 option. can i somehow put this in the code?

I believe compiler flags can't be embedded in the code itself, but you can certainly do that in a makefile for your program. This would also make your code a lot more portable. There are several tutorials on makefiles availible. I would just google for one.
