Hello,

I have a problem when compiling with the current trunk version (rev.
77432) of Boost.Accumulator:

In file included from
projects/boost-trunk/boost/accumulators/framework/accumulator_set.hpp:28:0,
                 from
projects/boost-trunk/boost/accumulators/accumulators.hpp:12,
                 ...
projects/boost-trunk/boost/accumulators/framework/accumulators/droppable_accumulator.hpp:
In copy constructor
'boost::accumulators::droppable_accumulator<Accumulator>::droppable_accumulator(const
boost::accumulators::droppable_accumulator<Accumulator>&)':
projects/boost-trunk/boost/accumulators/framework/accumulators/droppable_accumulator.hpp:173:54:
error: expected type-specifier
projects/boost-trunk/boost/accumulators/framework/accumulators/droppable_accumulator.hpp:173:54:
error: expected '>'
projects/boost-trunk/boost/accumulators/framework/accumulators/droppable_accumulator.hpp:173:54:
error: expected '('
projects/boost-trunk/boost/accumulators/framework/accumulators/droppable_accumulator.hpp:173:82:
error: expected ')' before 'const'

My system is:
OS: Fedora 14 x86_64
Compiler: GCC 4.6.1
Compiler's Flags: --ansi -pedantic -Wall -Wextra

I think you need to change line 173:
          : droppable_accumulator::base(*static_cast<droppable_accumulator::base
const *>(&that))

with the following (note the addition of "typename")
          : droppable_accumulator::base(*static_cast<typename
droppable_accumulator::base const *>(&that))

After this addition all seems to work.

Could you fix it, please?

Thank you very much.

Best,
