Hello,

Attempting to compile trunk (r35415) against GCC 4.6 (4.6.3, OSX 10.6, MacPorts provided) generates the following failure:

<pre>
/Users/luis/projects/oss/ruby/build/ext/readline
compiling ../../../ext/readline/readline.c
../../../ext/readline/readline.c: In function 'username_completion_proc_call':
../../../ext/readline/readline.c:1501:9: error: 'username_completion_function' undeclared (first use in this function)
../../../ext/readline/readline.c:1501:9: note: each undeclared identifier is reported only once for each function it appears in
make[2]: *** [readline.o] Error 1
make[1]: *** [ext/readline/all] Error 2
make: *** [build-ext] Error 2
</pre>

Readline installed is Readline 6.2 via MacPorts:

$ port installed | grep readline
  readline @6.2.000_0 (active)
