3973 | ||
3af0304a | 3974 | Some ``bugs'' may actually be no bugs at all. For instance, if you are |
475f9031 KH |
3975 | reporting that certain difference regions are not matched as you think they |
3976 | should, this is most likely due to the way Unix diff program decides what | |
3af0304a | 3977 | constitutes a difference region. Ediff is an Emacs interface to diff, and |
475f9031 KH |
3978 | it has nothing to do with those decisions---it only takes the output from |
3979 | diff and presents it in a way that is better suited for human browsing and | |
3980 | manipulation. | |
3981 | ||
3982 | If Emacs happens to dump core, this is NOT an Ediff problem---it is | |
3af0304a | 3983 | an Emacs bug. Report this to Emacs maintainers. |
475f9031 KH |
3984 | |
3985 | Another popular topic for reports is compilation messages. Because Ediff | |
3986 | interfaces to several other packages and runs under Emacs and XEmacs, | |
3987 | byte-compilation may produce output like this: | |
3988 | ||
3989 | While compiling toplevel forms in file ediff.el: | |
3990 | ** reference to free variable pm-color-alist | |
3991 | ........................ | |
3992 | While compiling the end of the data: | |
71296446 | 3993 | ** The following functions are not known to be defined: |
41d25ad0 | 3994 | ediff-valid-color-p, ediff-set-face, |
475f9031 KH |
3995 | ........................ |
3996 | ||
3997 | These are NOT errors, but inevitable warnings, which ought to be ignored. | |
3998 | ||
3999 | Please do not report those and similar things. However, comments and | |
4000 | suggestions are always welcome. | |
