Comment (by ryandesign):

 In addition, the problem may be that the earlier `#elif defined(F_GETFD)`
 path isn't being taken. On my macOS 12 SDK I see `F_GETFD` is defined in
 <fcntl.h> which filedescriptor.c does include but only if `HAVE_FCNTL_H`
 is defined. Maybe there is a bug in the configure script test and
 `HAVE_FCNTL_H` isn't getting defined; check your config.log.
