I will see if this works with COMMAND.COM. Alternatively, we could tell users to use "command /c config msdos", but I dislike such solutions unless there's no better way. > But defining DECL_ALIGN in config.h does not disable USE_LSB_TAG. Ouch, you are right. > The only > way, sort of modifying lisp.h of course, is to define USE_LISP_UNION_TYPE instead. I don't want to force use of USE_LISP_UNION_TYPE. I will add something to disable LSB tags, that could be something other platforms might need (we had a discussion in the past, and I think there was an agreement that there should be a general way to disable LSB tags). Thanks.
