Hi,

As a small note, even if you do disable optimisations -- If you have multiple 
source files, and are  working on a unix system with gcc, the "ccache" tool 
can be very handy to obtain faster build times...

Also don't forget that if you are building, you can make -j# to parallelize 
your build.
