No disrespect intended Mr. GCC maintainer, but I'm pretty sure that is
expected behavior. See "info gcc" in the -m128bit-long-double section:
*Warning:* if you override the default value for your target ABI,
the structures and arrays containing `long double' will change
their size as well as function calling convention for function
taking `long double' will be modified. Hence they will not be
binary compatible with arrays or structures in code compiled
without that switch.
Cygwin/newlib would need to be recompiled with this switch for proper
printf operation. Why are you trying to use this switch, Mathias?
