If you ever had to support, say, Mac OS X, which doesn't have /proc/, what would you have done? Use #ifdefs to isolate the platform-specific code (NSBundle, for example)?

Another approach would be to have a have clean #ifdef-less header wich contains function declarations and put the implementations in platform specific source files. For example, check out how Poco C++ library does something similar for their Environment class.
