Sounds like RLIMT_T_IS_LONG_LONG should be defined but isn't.
This is the test the shell is running to check the size:

#ifdef HAVE_SYS_TIME_H
#include <sys/time.h>
#endif
#include <sys/resource.h>
main(){struct rlimit r;exit(sizeof(r.rlim_cur) <= sizeof(long));}

Is rlim_cur not rlim_t, for some reason?  Or are the some flags
missing when this is compiled?

However, even that's not good enough since code doesn't currently
handle the combination of unsigned and long long.  That should be
easier to fix.
