Comment (by jeremyhu@…):

 Yeah, you can do that, but I'd rather know the underlying problem of where
 it's getting the prototype from.

 Can you please manually create the conftest.c as described in config.log,
 then compile it manually using the compile line mentioned in config.log?

 Use that as the reduced state to debug the problem from.

 I'd suggest using -E to preprocess conftest.c and then grep through the
 output to find out which file is providing the prototype.

 Also, please provide the output of echo | gcc-apple-4.2 -E -dM - | grep
 VERSION_MIN' on your system.  I want to confirm that the deployment target
 is set right.
