The real xgcc driver (host alpha-dec-vms) compiles and links a C program unaided on OVMX/Alpha: cc1, as, the port's ld wrapper (system() -> LIB$SPAWN -> DCL LINK -> LINK.EXE); DCL DUMP of HELLO.EXE equals the cross driver's image; RUN prints the line, status 1.
OVMX surface walls fixed (nothing in GCC/binutils):
Gate: xgcclink-gate, selftest with 10 negative controls; system() good/bad command asserted in the guest.
