+dnl @synopsis AX_CXX_CHECK_LIB(libname, functioname, action-if, action-if-not)
+dnl
+dnl The standard AC_CHECK_LIB can not test functions in namespaces.
+dnl Therefore AC_CHECK_LIB(cgicc, cgicc::Cgicc::getVersion) will always
+dnl fail. We need to decompose the functionname into a series of namespaces
+dnl where it gets declared so that it can be used for a link test.
+dnl
+dnl In the first version I did allow namespace::functionname to be a
+dnl reference to a void-argument global functionname (just wrapped in a
+dnl namespace) like its C counterparts would be - but in reality such
+dnl thing does not exist. The only global / static functions are always
+dnl made const-functions which is an attribute mangled along into the
+dnl library function export name. 
+dnl
+dnl The normal usage will ask for a test of a class-member function which
+dnl should be presented with a full function spec with arguments given in 
+dnl parentheses following the function name - if the function to test for 
+dnl does expect arguments then you should add default initial values in the 
+dnl prototype (even if they do not exist originally, these are used only 
+dnl locally to build a correct function call in the configure test script).
+dnl
+dnl In the current version if you do omit the parenthesis from the macro
+dnl argument then the macro will assume that you want to check for the
+dnl class name - which is really to check for default constructor being
+dnl exported from the given library name. 
+dnl
+dnl   EXAMPLE:
+dnl AX_CXX_CHECK_LIB(cgicc, [cgicc::HTTPCookie])
+dnl AX_CXX_CHECK_LIB(cgicc, [cgicc::Cgicc::getVersion () const],
+dnl AX_CXX_CHECK_LIB(boost_regex, [boost::RegEx::Position (int i = 0) const])
+dnl
+dnl Result:
+dnl Just as the usual AX_CXX_CHECK_LIB - defines HAVE_LIBCGICC 
+dnl and adds the libraries to the default library path (and
+dnl uses internally the normal ac_check_lib cache symbol
+dnl like ac_cv_lib_cgicc_cgicc__Cgicc)
+dnl
+dnl Footnote: The C++ language is not good at creating stable library
+dnl interfaces at the binary level - a lot of functionality is usually being 
+dnl given as inline functions plus there is hardly a chance to create opaque 
+dnl types. Therefore most C++ library tests will only do compile tests using
+dnl the header files. Doing a check_lib is however good to check the link
+dnl dependency before hitting it as an error in the build later.
