| 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. | |
