At the moment, building WeeChat triggers several thousand -Wstrict-prototypes diagnostics. This is due to its source code using an empty argument list for functions and function pointers that take no arguments, instead of explicitly declaring that they take no arguments by using a void list. This commit replaces all empty argument lists with a void list. Note that Ruby's headers also suffer the same problem, which WeeChat can't do anything to fix. Thus, building WeeChat with the Ruby plugin enabled will still issue approximately 30 such diagnostics.
