Need help: How to apply diffs generated by `cvs diff'

I tried to apply Daniel Pittman's patch created by `cvs diff' to my workspace using `patch -d /my/workspace'. However, it only patched the files in the root directory, like configure.in. Files in the lwlib/ directory couldn't be found by patch, even though the headers for those files look like: Index: lwlib/xlwradio.h =================================================================== RCS file: /usr/CVSroot/XEmacs/xemacs/lwlib/Attic/xlwradio.h,v retrieving revision 1.1.2.1 diff -u -r1.1.2.1 xlwradio.h --- xlwradio.h 1999/07/30 09:13:56 1.1.2.1 +++ xlwradio.h 1999/12/16 09:34:00 The documentation for `patch' indicates that it should look at the Index: line when patching. So why couldn't it find the file to patch? More generally, what is the procedure for applying patches generated by `cvs diff'? Why doesn't cvs generate headers that look like this instead? patch understands those. Index: lwlib/xlwradio.h =================================================================== RCS file: /usr/CVSroot/XEmacs/xemacs/lwlib/Attic/xlwradio.h,v retrieving revision 1.1.2.1 diff -u -r1.1.2.1 xlwradio.h --- lwlib/xlwradio.h 1999/07/30 09:13:56 1.1.2.1 +++ lwlib/xlwradio.h 1999/12/16 09:34:00 I'm using patch 2.5. Should I bother the CVS or the patch maintainers with a bug report? If so, which program is buggy? Martin
