Using a GPLed compiler and most of the GPL tools doesn't result in a 
requirement to licence under the GPL.  In particularly, gcc is often 
used to compile proprietary code.

Using GPL libraries does, except where those libraries implement 
functions that would normally be included with an operating system (e.g. 
the standard C library).

Some tools put a significant amount of template code into the output, 
but those are normally licensed under LGPL, rather than GPL.
