CC gethrxtime.o
cc-1020 cc: ERROR File = /usr/include/internal/signal_core.h, Line = 162
The identifier "timespec_t" is undefined.
extern int sigtimedwait(const sigset_t *, siginfo_t *, const timespec_t *);
^
1 error detected in the compilation of "gethrxtime.c".
*** Error code 2 (bu21)
The complete command line is:
cc -O -c99 -I. -I/home/haible/prefix-irix-cc/include -c -o gethrxtime.o
gethrxtime.c
timespec_t is defined in <sys/timespec.h>, and <sys/timespec.h> is included
by /usr/include/internal/signal_core.h.
Reduced test case:
========== foo.c =========
#include <sys/time.h>
==========================
$ cc -O -c99 -I. -c foo.c
fails
$ cc -O -c99 -c foo.c
succeeds
Looking at the output of "cc -O -c99 -I. -E foo.c | grep '#line'", here is what
happens. (I added the indentation.)

The problem is with gnulib's sys/select.h replacement. When I remove all
other gnulib generated .h files, the error persists.

Here comes the definition of timespec_t.
#line 161 "/usr/include/sys/time.h"
#line 1 "./sys/select.h"
#line 39 "./sys/select.h"
#line 179 "/usr/include/sys/time.h"

#line 93 "/usr/include/internal/time_core.h"
#line 5 "/usr/include/time.h"
#line 236 "/usr/include/sys/time.h"
#line 2 "foo.c"
So, the problem is that while <sys/timespec.h> is being included, we have an
include chain
/usr/include/sys/timespec.h
-> /usr/include/sys/types.h
-> /usr/include/sys/bsd_types.h
-> ./sys/select.h
-> /usr/include/signal.h
-> /usr/include/internal/signal_core.h
I'm adding this fix to gnulib.

sys_select: Avoid a syntax error regarding timespec_t on IRIX 6.5.

just include the system's header.
