Hello,
while working on a program i faced a problem.
i need only 20 bit , and having a 32 bit only waste more memory(12
byte), 24bit would much be better.
i need a uint24_t variable but gcc dont support it so i have to start
with uint32_t.
it would be very nice if gcc support such variables.
i made a little program and found that gcc (on i686) returned error.

Even if gcc had such a type I bet they would get aligned to 4-bytes on
most any target.
My guess is his won't be a high priority for folks. You could look at
how types are implemented in gcc, write a patch, make a case and see if
you can get it in.
