I think that the warning is accurate; the mangling of va_list has indeed
changed on ARM in GCC 4.4 in order to conform to the ARM ABI specifications.
There is an option to turn off warnings about PSABI issues; -Wno-psabi. I
think that option (if not some stronger option) should be used.
Oh, wait. Maybe we should not warn about this in a system header. That's
probably the right choice and a trivial change to arm_mangle_type.
Do you agree?
