22 * Borland C++ Fix/error check
23 * this has to go *before* we include any std lib headers:
25 #if defined(__BORLANDC__)
26 # include <boost/regex/config/borland.hpp>

49 * do C++ specific things in future...

64 /* Obsolete macro, use BOOST_VERSION instead: */
65 #define BOOST_RE_VERSION 320
68 #if defined(_UNICODE) && !defined(UNICODE)
73 * Fix for gcc prior to 3.4: std::ctype<wchar_t> doesn't allow
74 * masks to be combined, for example:
75 * std::use_facet<std::ctype<wchar_t> >.is(std::ctype_base::lower|std::ctype_base::upper, L'a');
79 # define BOOST_REGEX_BUGGY_CTYPE_FACET
83 * Intel C++ before 8.0 ends up with unresolved externals unless we turn off
84 * extern template support:
86 #if defined(BOOST_INTEL) && defined(__cplusplus) && (BOOST_INTEL <= 800)
87 # define BOOST_REGEX_NO_EXTERNAL_TEMPLATES
90 * Visual C++ doesn't support external templates with C++ extensions turned off:
92 #if defined(_MSC_VER) && !defined(_MSC_EXTENSIONS)
93 # define BOOST_REGEX_NO_EXTERNAL_TEMPLATES
97 * If there isn't good enough wide character support then there will
98 * be no wide character regular expressions:
100 #if (defined(BOOST_NO_CWCHAR) || defined(BOOST_NO_CWCTYPE) || defined(BOOST_NO_STD_WSTRING))
