gcc has binary literals such as 0b00100001 as an extension.  Since it is
in popular use, has an existing implementation, and no signs of
conflicting with existing code, it is probably a good candidate for
future C standards.

And although it is off-topic in both C and Fortran groups, 0b001 style
binary literals are due to be in C++14.
