I believe this is a compiler error and the only way I'm aware of to  
work around it is to perform this computation:

     const bool no_padding = bits_per_block == CHAR_BIT * sizeof(Block);
     const mode m = table_width >= CHAR_BIT && no_padding
                      ? access_by_bytes : access_by_blocks;

using class static const members instead of function-locale const  
variables.

Looks like <locale> is not getting included.
