How long is a piece of string?

Of course, the answer depends on your system. Building gcc from scratch on a 1 GHz x86 takes on the order of 3 hours, IIRC -- it's been a while since I did that.

Very dependent on CPU speed. You must have 64 MB of memory to contemplate building gcc; you must have 1 GB of virtual memory available; if you have more than 512 MB of physical memory and can use it as file cache, it will speed things up significantly. There are probably individual files which use 500 MB of virtual memory to compile, while most files will take between 10 MB and 100 MB.

(Most of my experiences building gcc were in the pre-3.0 phase, so it's possible things have gotten a lot worse lately...)

Yes, gcc will bootstrap itself on just about anything that can call itself a C compiler.
