Subject: options parsing madness
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8affbf5a246d00997a19bb586d0b7155e024d81d;p=nethack

options parsing madness

I should have reenabled curses before committing an earlier change;
it broke compile.

Make all optfn_FOO() be static in options.c;
fix newly added prototype for optfn_cursesgraphics();
fix conditionals for optfn_palette(), both prototype and function.

Also, add missing prototype for a sound routine.
