Such questions do need to be asked if the C standard were to drop
support for "obsolete" hardware for future versions.  I am confident
that systems with padding bits are sufficiently obsolete and obscure
that they can be dropped - but I would definitely want the committee to
investigate such points properly, and not just take the word of some guy
off Usenet!

Perhaps the more significant change is that currently the C standards
document are each written to succeed and replace previous versions.
There is only one current valid ISO C standard - the version known as
C11.  A "C compiler" made today has to follow that version of the
standard.  If a future C standard dropped support for some older
hardware, then there would really need to be a fork in the standards -
so that C11 would still be a valid standard for old systems, with C20
(or whatever) going onward for modern ones.

No, 64-bit int is not a sensible idea (IMHO).  Extended integer types
could solve some of the problems it would create, but at significant
effort to toolchain authors, library writers (someone has to make a
"printf" that supports the different sizes in some way), and significant
inconvenience in data exchange.  It is data exchange (by network
protocols, file formats, etc.) that drives the need for standardisation
here.

And what is to be gained with 64-bit int?  There is some hardware that
can operate more efficiently on a 64-bit object than a 32-bit object -
but such hardware is niche or obsolete (i.e., old Cray machines), and
therefore excluded.  Is there any software benefit in having 64-bit int?
 I think not - it is rare indeed that you actually need such a large
integer type, and C already has perfectly good ones that you can use in
that case (int64_t and long long int).

It is not a coincidence that the only systems with 64-bit int are
ancient, and pre-date the common usage of 64-bit processors.
