--------------------------+------------------------
 The build fails on 10.7 because the `__FBSDID()` macro isn’t defined by
 <sys/cdefs.h> prior to the 10.8 SDK (and only for compatibility—the
 definition is empty). The error message is from clang trying to interpret
 the macro usage as a function declaration.

 Maybe this is something to easily put in legacysupport, unless this is too
 simple to be worth the effort. A few other ports work around the same
 issue: rpcgen-mt, developer_cmds, libpdel, bsdiff, fortune,
