Fix the following compilation warnings on platforms where
sizeof(struct timeval.tv_usec) < sizeof(long):
xettimeofday.c: In function ‘main’:
xettimeofday.c:76:16: warning: overflow in implicit constant conversion [-Woverflow]
tv->tv_usec = (long) 0xbadc0dedfacefeedLL;
xetitimer.c: In function ‘main’:
xetitimer.c:170:28: warning: overflow in implicit constant conversion [-Woverflow]
p_new->it_value.tv_usec = (long) 0xbadc0dedfacefeedLL;
In file included from utimes.c:38:0:
xutimes.c: In function ‘main’:
xutimes.c:110:18: warning: overflow in implicit constant conversion [-Woverflow]
tv[1].tv_usec = (long) 0xbadc0dedfacefeedLL;
futimesat.c: In function ‘main’:
futimesat.c:121:18: warning: overflow in implicit constant conversion [-Woverflow]
tv[1].tv_usec = (long) 0xbadc0dedfacefeedLL;
In file included from _newselect.c:35:0:
xselect.c: In function ‘main’:
xselect.c:94:16: warning: overflow in implicit constant conversion [-Woverflow]
tv->tv_usec = (long) 0xbadc0dedfacefeedLL;
^
* tests/futimesat.c (main): In initialization of struct timeval.tv_usec,
change explicit cast from (long) to (suseconds_t).
* tests/xetitimer.c: Likewise.
* tests/xettimeofday.c: Likewise.
* tests/xselect.c: Likewise.
* tests/xutimes.c: Likewise.
