These similar methods exist in v2_5_5:

have_func(func, headers = nil, &b) public

Returns whether or not the function func can be found in the common header files, or within any headers that you provide. If found, a macro is passed as a preprocessor constant to the compiler using the function name, in uppercase, prepended with ‘HAVE_’.

For example, if have_func(‘foo’) returned true, then the HAVE_FOO preprocessor macro would be passed to the compiler.
