    TODO: All the libomp source code uses pid_t type for storing the result of getpid(), it is good.
    But often it printed as "%d", that is not good, because it ignores pid_t definition (may pid_t
    be longer that int?). It seems all pid prints should be rewritten as

        printf( "%" KMP_UINT64_SPEC, (kmp_uint64) pid );

    or (at least) as

        printf( "%" KMP_UINT32_SPEC, (kmp_uint32) pid );

    (kmp_uint32, kmp_uint64, KMP_UINT64_SPEC, and KMP_UNIT32_SPEC are defined in "kmp_os.h".)
