Re: printf enhancement
Since it is possible to use the 0b prefix to specify a binary number in GCC/C++, will there be any resistance to add %b format specifier to the printf family format strings? You can do that yourself by using the hook facility for printf, see (libc) Customizing Printf in the GNU C library manual; this is a GNU extention and not supported by ISO C.

printf enhancement
Since it is possible to use the 0b prefix to specify a binary number in GCC/C++, will there be any resistance to add %b format specifier to the printf family format strings? Best regards Piotr Wyderski
