Follow-up Comment #4, bug #52858 (project octave):
The last time I looked they are not provided by gnulib. Gnulib does provide
some M4 autoconf code to check whether they are available, and add "-lrt" if
necessary, which is what we are already using.
Gnulib does provide a function called "gettime" which calls either nanotime
(BSD function?), clock_gettime (POSIX function), or gettimeofday. But this
only works as a wall clock function, this wouldn't work as a replacement for
process time as reported by getrusage for example.
