Couple hundred megabytes. It's still a lot larger than Orca/C was on my Apple IIgs (1 or 2 3.5" floppies?), but then again, compilers come with a lot of libraries these days.
Does it bother you for rational or irrational reasons? It bothers me for irrational reasons - it feels like it's too much, but really, I'm using about 65 GB of a 500 GB disk. So I tell myself to ignore that feeling and just install Xcode because it's the most efficient means of getting developer tools on my Mac.
I used osx gcc installer for a bit, but had to go back to xcode when I needed things like opengl headers, which are not otherwise available. Frustrating, for sure.
The size of Xcode annoys me too, since I never use it. So I've been using this GCC install on my Mac: https://github.com/kennethreitz/osx-gcc-installer
