Sorry for asking again, but I tried CW9.2 evaluation version and it
*doesn't* give errors. Since I'm worried that introducing two new
class templates can trigger warnings/errors with other compilers,
Would it be ok to write e.g.

  const bool no_padding = bits_per_block == CHAR_BIT * sizeof(Block);
  const bool table_is_large_enough = table_width >= CHAR_BIT;

  return do_count(
                  m_bits.begin(), num_blocks(), Block(0),
                  (mode_to_type<
                           (no_padding && table_is_large_enough?)
                           access_by_bytes : access_by_blocks
                   >*) 0
                 );

?

This one is odd. I see that the command line used for regression
testing includes "-runtime dmd", and our metrowerks config file has

// locale support is disabled when linking with the dynamic runtime
#   ifdef _MSL_NO_LOCALE
#     define BOOST_NO_STD_LOCALE
#   endif 

Since I test for BOOST_NO_STD_LOCALE before #including it may well be
that <locale> is not getting included :) But why everything works with
CW 9.2 instead? Can you please confirm that _MSL_NO_LOCALE is defined
for version 8.3 and not for 9.2?

Thanks,

Genny.
