Ah, ok, that is a problem then. As you probably know, the Mac's default filesystem is case-insensitive, while Subversion repositories are case-sensitive. And your repository seems to think there are two files in it whose names differ only in case, which is of course a situation that then cannot be correctly represented on your Mac's filesystem. Is it your intention to delete just one of these files (either Align.c or align.c), or both of them? I recommend you do whatever it is via direct repository URLs, not in a working copy.
