A compile with sparse (make C=1) shows the following warnings: util_opt.c:42:19: warning: symbol 'util_opt_l' was not declared. Should it be static? util_prg.c:28:19: warning: symbol 'util_prg_l' was not declared. Should it be static? util_opt_l and util_prg_l are not used anywhere, and also not declared in any header file. Looks like they are superfluous, remove them.
