That's interesting. None of the compilers I use (Sun CC, g++

several levels of optimization, and the possibility to turn off

Yes you are right, but in VC++ when you create a new project by
default there are 2 configs, a debug config with optimisations off and
a release config with optimise on. Of course you can change these
settings.
I think you're referring to the Visual Studios IDE, and not
VC++; I use VC++ from time to time, and I've not seen two
"default" configurations---VC++ is very much like g++ or Sun CC
in that it has hundreds of command line options, and in any real
production work, the defaults are absolutely worthless; you need
tens of options to get anything useful.
As for defaults in general: you really should carefully read the
documentation of the tools you are using, particularly critical
ones like the compiler, and decide explicitly which options are
relevant to your application. I've never found the defaults to
be appropriate, and it's usual that different applications need
a different set of options.
