I'm suddenly feeling really stupid. Why in the world did I wait as long as I did? I mean, I know they're useful and make life much nicer when you're forced to work with Windows, but how could I forget what a world of difference it makes? I should have done this the day I got the new work computer.
Either way, I've got everything installed, configured, and ready go to. It's such a relief to have a semi-proper set of development tools. Now I can write a proper makefile, instead of this stupid DOS batch file. ;-)
