Subject: fix "function declaration isn't a prototype" warnings from -Wstrict-prototypes
X-Git-Tag: LAST_LIBGRAPH~32^2~7891
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f30b9eca9d721f4ab08e344f16b7eb454bb2c3ac;p=graphviz

fix "function declaration isn't a prototype" warnings from -Wstrict-prototypes
    mostly by using (void) instead of () for functions with empty parameter lists.
