Problem with fd_set configuration in X11R7.0-RC0/libs/xproto-7.0

[Gregor Richards]

In X11R7.0-RC0, in xproto-7.0, the configuration is failing on HPUX 
11.00 because it can't find the fd_set struct. It's trying to #include 
<sys/select.h>, which does the trick on a number of systems (at least 
GNU/Linux and Solaris), but fd_set seems to be in sys/types.h on HPUX. 
Furthermore, sys/types.h actually includes sys/select.h on both Solaris 
and glibc (GNU/Linux). It seems like it would be more portable to look 
in sys/types.h for fd_set rather than sys/select.h.  Is there a reason 
why it's using sys/select.h instead of sys/types.h right now?

Thanks for any response!
