>Description:
The code /usr/src/usr.bin/getconf/limits.gperf doesn't correctly handle unsigned constants.
Since it uses an intmax_t for all included variables, any value larger than INTMAX_MAX is printed incorrectly.
So, on my machine it prints -1 for ULLONG_MAX when it should print:
18446744073709551615 (defined in <machine/_limits.h> to be 0xffffffffffffffffULL)
if the desktop calculator isn't fooling me

>How-To-Repeat:
getconf ULLONG_MAX
>Fix:
I could submit a patch if there's a minimal guarantee that I won't lose my time...
