Hello, I'd like to know if there is any standard way of dealing with a problem which arises when you use AC_CHECK_FUNCS with a function whose name begins with an underscore (e.g. _snprintf) and then use the result of the test in C++ code. To be precise, the problem is that AC_CHECK_FUNCS would define a symbol HAVE__SNPRINTF which, according to 17.4.3.1.2 of the ISO C++ standard, is a reserved symbol in C++ program and so can't be used. Of course, it's pretty simple to work around this problem by using AC_CHECK_FUNC instead but as I'm surely not the first one to be in such situation, I'd like to know: 1. What do the others do? Just ignore this problem (hoping that HAVE__XXX is not really reserved) or is there something better? 2. Is there any more or less standard convention for naming HAVE symbol for such functions (HAVE_UNDERSCORE_SNPRINTF looks a bit ugly)? 3. Is it worth looking into patching autoconf to change AC_CHECK_FUNCS to not generate reserved symbols for such functions or if such patch would not be accepted anyhow (e.g. because of backwards compatibility)?
