The following (and attached) patch quelches three warnings. Documenting the parameter in apr_atomic.h looks straightforward enough. As for the apr_os_proc_mutex structure, I (but who am I) would expect that to be opaque to the user, but os/unix/unixd.c in Apache directly accesses the crossproc parameter. Anyway I don't see any commands in doxygen to define opaque members, other than to wrap the members into an ifdef that does not affect compilation but does cause doxygen to look the other way. For now I opted for some benign prose.
Let me know if opaquization (is that a word?) would be a better option.
