[Roadster] Issues compiling Roadster on Mac OS X: mainwindow.c throws "parameter name omitted" errors

[Matthew Vaughn]

Dear Ian and Jeff,

I just got around to trying Jeff's patch. It worked, and I think the  
basic compile went OK. However, the overall build failed in the libs  
section with a load of linker errors. It looks to me like libraries  
in /usr/lib are over-riding the ones I built in /opt/local/lib  
despite the fact that I never specified to use /usr/lib at all. I  
haven't had much time to try and work around this, but a quick  
perusal of google suggests that this is a common issue with the  
Darwin linker.

Cheers,

Matt
