Just moved to Fedora Core 1 ... I am porting my old OpenGL code and have had good success so far. Problem is that the gdb debugger sux0rz wrt the M$ Dev Studio debugger.

You could try DDD. It's just a frontend to gdb, but it has visual breakpointing and step functionality, plus other cool features (it's visual). It's as close to the MS debugger as I've ever seen (on Linux/BSD).
Also, make sure to compile with -g so debugging information gets left in the object files.
