Hi Eli,

this is probably a silly question to ask, because I don't know the
internals of Emacs so well; it's just a thought which I had though.

Are there plans to make the buffer size use one of the types with "at
least X bits", like uint32_t or uint64_t?  Do you think there is a good
reason *not* to do this (i.e. an absurd performance penalty on some of
the supported platforms)?
