If you are to patch a file inside of filters/ and that patching creates a .c.orig file, it will get installed along with other .c files. This is super minor and nit-picky but it probably shouldn't do this. I'm not 100% sure but I think it has something to do with line 30 of GNUmakefile. Thank you!

On NetBSD, we don't need the define in filters/wrap.c line 4. If it is left there, we get errors about not having locale_t defined. Removing it will fix these errors. I'm not sure if this same thing happens on other BSDs or not.
