It is: MSVC.NET 7.0.9466.

My colleague sorted the stuff now out, in config.hpp (line 41):

Before:
// For the DLL support contributed by Stephen Naughton
# ifdef ANTLR_EXPORTS
#	undef ANTLR_API
#	define ANTLR_API __declspec(dllexport)
# else
#	undef ANTLR_API
#	define ANTLR_API __declspec(dllimport)
# endif


Should be:
// For the DLL support contributed by Stephen Naughton
# ifdef ANTLR_EXPORTS
#    undef ANTLR_API
#    define ANTLR_API __declspec(dllexport)
# elif defined(ANTLR_IMPORTS)
#    undef ANTLR_API
#    define ANTLR_API __declspec(dllimport)
# else
#   undef ANTLR_API
#   define ANTLR_API
# endif

Without you get the following errors:
antlr\BaseAST.cpp(312) : error C2201: 'nullASTptr' : must have
external linkage in order to be exported/imported
antlr\TreeParser.cpp(39) : error C2491: 'antlr::TreeParser::ASTNULL' :
definition of dllimport static data member not allowed
antlr\Token.cpp(18): error C2491: 'antlr::Token::badToken' :
definition of dllimport static data member not allowed
antlr\Token.cpp(18): error C2720: 'antlr::Token::badToken' :
'antlr::Token::' storage-class specifier illegal on members
...

Where can I get 2.7.3?
