Well, if it is the same then pack your current dev dir where you extracted it and send it to me, I want to check if the current directory structure that you have is right...maybe its not being unpacked well resulting in errors when compilating
To check that I must have not the zip in the FBA site, i need the one you have in your pc to check if its 100% right, if it compiles fine then definitely its a Window Vista issue with MinGW.
SeeYaa!
