I just noticed the new configure.ac. This is a great idea: I always thought it was unfortunate that when a new user tries to compile simutrans from source, the first thing they have to do is learn about a custom build scheme, edit a config file, etc. I hope that this mode becomes the default!
Anyhow, here are two short patches related to compilation on OS X.
1. Autoconf didn't quite work out of the box on my macbook, since it tried to compile an Objective-C++ header file without switching to objc++ mode. (See patch file or Github for full commit message.)

2. Compilation didn't succeed with multithreading enabled. I think this is only a problem on Lion and above. (Again, patch for full commit message.)

Edit: just noticed I used "and" instead of "&&" in patch #2. Bizarrely, the preprocessor seemed to accept it? Anyhow, patch and link updated.

and is a valid C++ keyword, with the same meaning as
&&. I don't remember if it is valid C as well, and I don't know about Objective-C.
THank you, incorporated
