| | | | | | | | | | | udhcpc: make UDP packet sending the same as raw sending in regards to error messages. Minor code size shrink. Total size grows due to added messages: text data bss dec hex filename 770312 683 7244 778239 bdfff busybox_old 770327 683 7244 778254 be00e busybox_unstripped

| | | | | | | | | | | | | | | | | | | | | | This is a bulk spelling fix patch against busybox-1.00-pre10. If anyone gets a corrupted copy (and cares), let me know and I will make alternate arrangements. Erik - please apply. Authors - please check that I didn't corrupt any meaning. Package importers - see if any of these changes should be passed to the upstream authors. I glossed over lots of sloppy capitalizations, missing apostrophes, mixed American/British spellings, and German-style compound words. What is "pretect redefined for test" in cmdedit.c? Good luck on the 1.00 release! - Larry
