-dnl @synopsis AC_FUNC_SNPRINTF
-dnl
-dnl Checks for a fully C99 compliant snprintf, in particular checks
-dnl whether it does bounds checking and returns the correct string
-dnl length; does the same check for vsnprintf. If no working snprintf
-dnl or vsnprintf is found, request a replacement and warn the user
-dnl about it. Note: the mentioned replacement is freely available and
-dnl may be used in any project regardless of it's licence (just like
-dnl the autoconf special exemption).

-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.
