GCC installation på TRU64 v5.0

Jeg har et seriøst problem... Jeg kan ik compile GCC, og jeg skal bruge det til nogle andre ting... anyways... her er fejlen...cc: Error: cp/decl.c, line 571: In this statement, \"(cfun?((struct cp_language_f
unction ...)(cfun->language))->bindings:scope_chain->bindings)\" is not an lvalue

Jeg ved at der evt er et problem netop med GCC på TRU64, men jeg har ik fundet nogle løsning, nogen som kan hjælpe lille mig?

Og, det er den nye version af GCC, jeg har endda prøvet med snapshots fra 4-12-2000
og den laver samme fejl..har og prøvet ældre versioner...
