C23 Bit-precise integer types 
(http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2763.pdf) allow 
programmers to explicitly state their intent on how many bits are 
needed; but since they are addressable, they need padding bits when 
their width is not a multiple of CHAR_WIDTH. Some implementations might 
use more padding for alignment. Where there is a need to save memory, 
they are thus not suitable. Using bit-precise integer types in 
bit-fields solves this issue.

So, I'd like to see bit-fields of bit-precise integer types in C:
