These changes cause genapi.cc to use whichever of clock_gettime() or
gettimeofday() are available. This prevents compilation errors on
systems where clock_gettime() is not available.
gcc/cobol/ChangeLog:
PR cobol/119975
* genapi.cc (parser_intrinsic_call_0): Use get_time_64()
function.
* genutil.cc (get_time_64): Definition created.
* genutil.h (get_time_64): Declaration created.
