I have an iphone project with speex built in.  I had to add these macros to the preprocessor definitions:

Setting: GCC_PREPROCESSOR_DEFINITIONS
Values: USE_KISS_FFT=1 EXPORT= FIXED_POINT=1

The EXPORT macro takes care of the "expected '=',',',';','asm' or '__attribute__' before 'void'" error by simply making the word EXPORT disappear throughout the source; I have no idea if this is the best way to handle it or not, it seems reasonable to me since I'm building it into an executable, but I admit to being in way over my head when it comes to building C libraries.

After that I had to add the speex include directory to the project's search path like this:

Setting: HEADER_SEARCH_PATHS
Value: $(PROJECT_DIR)/speex/include
(Assuming, of course, that you've copied the whole speex project folder into your project directory.)

As I recall that was pretty much all it took to get XCode to build it.  I don't know if it's the "proper" way to do it, but it works.
