[PATCH] find RLIM_NLIMITS correctly on Cygwin

[Jun T <takimoto-j@xxxxxxxxxxxxxxxxx>]

On Cygwin, <sys/resource.h> has lines like:

#define RLIMIT_NLIMITS  7       /* upper bound of RLIMIT_* defines */
#define RLIM_NLIMITS    RLIMIT_NLIMITS

but rlimits.awk fails to find the value of RLIM_NLIMITS
(and sets ZSH_NLIMITS to zero).
