[boost] boost.regex v4 compilation issue on VC++ 6 (and correction suggestion)

    Compilation of boost regex v4 (from the CVS) fails with the following
error under VC6:

f:\projects\cpptool\cppparser_dependencies\cppparser\include\boost\regex\v4\
basic_regex.hpp(221) : error C2143: syntax error : missing ',' before '<'

f:\projects\cpptool\cppparser_dependencies\cppparser\include\boost\regex\v4\
basic_regex.hpp(298) : see reference to class template instantiation
'boost::reg_expression<charT,traits,Allocator>' being compiled

    Looking at the sources (inside template reg_expression definition):

 bool BOOST_REGEX_CALL operator==(const reg_expression& e)const
 { return compare(e) == 0; }
 bool operator != (const basic_regex<charT, traits, Allocator>& e)  // <<<
*** error here ***
 { return compare(e) != 0; }

    basic_regex is defined later in the source, hence the compilation error.
Also, the fact that operator == & != have different prototype is very
suspicious... Using reg_expression instead or basic_regex would fix the
error.
