warning: comparison is always false due to limited range of data type

[Oskar Liljeblad]

What's the proper way to fix these warnings?

quotearg.c: In function `quotearg_n_options':
quotearg.c:586: warning: comparison is always false due to limited range of
data type

argp-help.c: In function `make_hol':
argp-help.c:430: warning: comparison is always true due to limited range of
data type
argp-help.c: In function `hol_append':
argp-help.c:831: warning: comparison is always true due to limited range of
data type

I get them on x86_64-unknown-linux-gnu.

Regards
