pkgs/misc/drivers/epkowa/sscanf.patch

   1 The "%as" verb requests sscanf to allocate a buffer for us. However,
   2 this use of 'a' has been long deprecated, and gcc doesn't support it
   3 in this manner when using -std=c99. The modern replacement is "%ms".

   5 Without this change, iscan couldn't read the interpreter file, in turn
   6 breaking all scanners that require plugins.
