Re: [MiNT] GCC 4.2.2 and binary compatibility

So what do you think about removing the alignments, for structure
members and stack parameters ? Does it break some compatibility ?

Alignment is part of the ABI.  If you change it you are creating an
incompatible ABI.

There is a well-known ABI for calling TOS/MiNT.
But is there a standard ABI for internal data structures alignment, as well as function calls, eventually across the static libraries ?
Is GCC 2.95 the de-facto standard ?
