That option is almost equivalent to:

	-debug -prefix $PWD -DQT_INTERNAL_BUILD

So it sets the default to debug mode build, it configures the prefix for the 
current directory (that is, no need for make install) and it also adds one 
#define that, in turn, causes some more symbols to be exported.

It also turns on an extra qconfig option, which enables extra tests (that is, 
all the unit tests that require private symbols).

No.

Yes, you can, *after* this switch.

It's your choice. We don't use it for our own development.

The same way as before. Nothing changes.

The difference is that a "non-install" build means the build is the 
installation. Just set the variables to the build.

Set PATH to the bin directory in the build dir.

Your options are:
1) get a faster computer
2) get a build farm (use your co-workers' machines for that)
3) don't build the entirety of Qt

If you just want to experiment, start with just the src subdir. You may also 
want to disable webkit, since that cuts in half the time required to build 
src.
