Thanks, but this version doesn't compile since:
rlimits.c: In function 'printulimit':
rlimits.c:398:5: error: duplicate case value
     case RLIMIT_NTHR:
     ^
rlimits.c:379:5: error: previously used here
     case RLIMIT_PTHREAD:
     ^

The #else here is for RTPRIO, so we have cases for RLIMIT_NTHR and
RLIMIT_PTHREAD in the same case statement.
