My luck with compiling stuff sucks, so not to my surprise I have stumbled up the following error:

Code:
/System/Library/Frameworks/Kernel.framework/Headers/sys/unistd.h:236: warning: type defaults to 'int' in delcaration of 'sigset_t'
/System/Library/Frameworks/Kernel.framework/Headers/sys/unistd.h:236: error: parse error before '*' token
When running the "make RC_OS=macos kld_build" command as per the instructions here: http://developer.apple.com/documentation/D..._section_3.html

Help anyone?
