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. | |
