Revised GCCE workaround for Bug 2926 - must use :zip export to ensure that the various files are present before any builds are attempted, otherwise there is "no rule to make usrt3_1.lib" and no attempt is made to link any executables even after the extension makefiles are executed.

EXPORTS
Init @ 1 NONAME
FunctionCount @ 2 NONAME
CallFunction @ 3 NONAME
SetClose @ 4 NONAME
