* Create an improved function search macro, and use it to look for res_query.Diego 'Flameeyes' Pettenò2008-10-281-0/+82
Instead of using AC_SEARCH_LIBS or AC_CHECK_LIB, create a new macro to search for function in different libraries; this is needed since the function name might just be a (preprocessor) macro for another symbol. The new macro is released under GPL2 (or later) + exception, and allows to provide a custom source code to use to test for the function.
