numeric/conversion/converter_policies.hpp won't build with gcc -fno-exceptions

[Markus Laker <markusl@…>]

Using gcc -fno-exceptions:

In file included from /home/markusl/work/unicorn/1/libs/manspan/Ibspanfuncs.cpp:17:

/home/markusl/work/unicorn/1/include/x86_64_bali/boost/numeric/conversion/converter_policies.hpp: In member function 'void boost::numeric::def_overflow_handler::operator()(boost::numeric::range_check_result)':

/home/markusl/work/unicorn/1/include/x86_64_bali/boost/numeric/conversion/converter_policies.hpp:162: error: exception handling disabled, use -fexceptions to enable

The attached patch fixes the problem.

I've run into this error as well. Is there a compelling reason for not using a boost exception here?

Likewise, I'm hitting this problem in fedora boost-devel-1.44-8-fc14.x86_64, please fix this issue please.

(In [77234]) Fixes #5731, fixes #5076, fixes #5393, fixes #5800 Now numeric_cast (and lexical_cast) can be compiled with disabled exceptions
