- Subject: [RFC/AIX] xm-aix4.h - get rid of #undef fd_set & select #include
config/xm-aix4.h contains the following definitions:
| /* 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.
| */
| #undef fd_set
|
| #include <sys/select.h>
On our systems (AIX 4.3.2 and 5.1), this type is defined in time.h
typedef struct
#ifdef _ALL_SOURCE
fd_set
#endif /* _ALL_SOURCE */
{
long fds_bits[__NUM_ENTRIES]; /* bitmask for open file descriptors */
} fd_set;
I couldn't find config/rs6000.mh, nor the original comment. So I wonder
if we wouldn't be able to delete these two.
I can give it a try, but would I miss something?
