| /* 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. |
