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