3949 | ---------------------- | |
3950 | ||
3af0304a | 3951 | Some ``bugs'' may actually be no bugs at all. For instance, if you are |
475f9031 KH |
3952 | reporting that certain difference regions are not matched as you think they |
3953 | should, this is most likely due to the way Unix diff program decides what | |
3af0304a | 3954 | constitutes a difference region. Ediff is an Emacs interface to diff, and |
475f9031 KH |
3955 | it has nothing to do with those decisions---it only takes the output from |
3956 | diff and presents it in a way that is better suited for human browsing and | |
3957 | manipulation. | |
3958 | ||
3959 | If Emacs happens to dump core, this is NOT an Ediff problem---it is | |
3af0304a | 3960 | an Emacs bug. Report this to Emacs maintainers. |
475f9031 KH |
3961 | |
3962 | Another popular topic for reports is compilation messages. Because Ediff | |
3963 | interfaces to several other packages and runs under Emacs and XEmacs, | |
3964 | byte-compilation may produce output like this: | |
3965 | ||
3966 | While compiling toplevel forms in file ediff.el: | |
3967 | ** reference to free variable pm-color-alist | |
3968 | ........................ | |
3969 | While compiling the end of the data: | |
3970 | ** The following functions are not known to be defined: | |
41d25ad0 | 3971 | ediff-valid-color-p, ediff-set-face, |
475f9031 KH |
3972 | ........................ |
3973 | ||
3974 | These are NOT errors, but inevitable warnings, which ought to be ignored. | |
3975 | ||
3976 | Please do not report those and similar things. However, comments and | |
3977 | suggestions are always welcome. | |
