But it is a gcc implementation consideration. We document in esxtend.texi
what it means, so we'd better implement it properly to do just that.
And the primary use for DECL_PACKED (field) is to indicate if
__attribute__ ((packed)) has been used. I we need to have a pragma that
indicates a half-baked packedness, that information should be passed somewhere
else.
The code we currently have is indeed broken, gcc.dg/bitfld-3.c and gcc.dg/bitfld-4.c
fail. I'm currently testing a patch (which just disables the alignment for
DECL_PACKED fields, just like in the other cases).
