[cfe-dev] Microsoft ABI Support vs. ms_struct & Removing -mms-bitfields

[Anton Korobeynikov]

> Can we get rid of mms-bitfields in favor of ms_struct?  Is anyone using mms-bitfields?  Because mms-bitfields is global, it applies to the entire #include chain for a TU and can cause system structs etc to be laid out incorrectly and potentially silently break standard library interfaces/linking to TUs that don't have mms-bitfields, etc.
Will this break compatibility with mingw? If yes, then mms-bitfields
should stay.
