Hi devs,
During my pdp porting effort I have been able to solve the problem with mingw compilation. The trick is to add a flag to gcc, it is called -mms-bitfields.
Using this, t_object has the same size, with visual studio and gcc.
Thought the info might be useful, sorry if it is already known. I propose to add this flag under windows for mingw compiled pd and all externals.
