I'm trying to build wineasio 0.90 on osx.  So far can't get past some ELF assember code injection which I believe is a work around for COM.  Somehow whatever is in wineasio's asio.c file is not compatible with Mac.  Anyone have an idea how I might fix this?

Here is the compiler error and below that the code I think causing the problem:

Error:

Code:
