  22  * # The IBM version of /usr/include/rpc/rpc.h has a bug -- it says
  23  * # `extern fd_set svc_fdset;' without ever defining the type fd_set.
  24  * # Unfortunately this occurs in the vx-share code, which is not configured
  25  * # like the rest of GDB (e.g. it doesn't include "defs.h").
  26  * # We circumvent this bug by #define-ing fd_set here, but undefining it in
  27  * # the xm-rs6000.h file before ordinary modules try to use it.  FIXME, IBM!
  28  * MH_CFLAGS='-Dfd_set=int'
  29  * So, here we do the undefine...which has to occur before we include
  30  * <sys/select.h> below.
