Last time I supped, I got the following "warnings":

SUP: File server unable to transfer file src/gnu/usr.bin/gdb/gdb/arch/vax/tm-vax.h
SUP: File server unable to transfer file src/gnu/usr.bin/gdb/gdb/arch/vax/vax-tdep.c
SUP: File server unable to transfer file src/gnu/usr.bin/gdb/include/opcode/vax.h

Not horribly inconvenient to me personally, but it would be nice if the
upgrade time was updated.
