This patch declares a number of SUSv3 functions found in sys/unistd.h unconditionally. It also changes the prototype of usleep and sync to match SUSv3. Does any target need to override the standard prototype, or can this be fixed globally?
Cheers, Shaun
* libc/include/sys/unistd.h (ftruncate, truncate, ualarm, usleep, gethostname, mktemp, sync): Declare these SUSv3 functions unconditionally. (usleep): Change the prototype to match SUSv3. (sync) [!__rtems__]: Ditto.
