[Bug preprocessor/23479] New: Implement binary constants with a "0b" prefix

["j at uriah dot heep dot sax dot de" <gcc-bugzilla at gcc dot gnu dot org>]

It is suggested to implement binary contants as a GCC extension to the
language.  This is a frequently requested item in microcontroller
environments, and several other compilers already implement it.  The
commonly used prefix is "0b", as this does not contradict the standard
C syntax, and allows for an easy private extension to the language.

Several distributions of AVR-GCC (including the popular "WinAVR" one,
and the FreeBSD port of AVR-GCC) have been shipping with this
extension for quite some time, and general user feedback about it is
positive.
