There's a little catch-22 that we're running into in trying to get --enable-layout to work. I have a patch that seems to fix --enable-layout again, but there is a potential problem: If one specifies --enable-layout=foo then that layout profile will completely override other settings like --prefix. I don't see this as a problem, since one must explicitly introduce --enable-layout (which in and of itself can completely control all buildtime/installtime paths).
Due to some issues with autoconf, it wouldn't be possible to simply save and restore the --prefix -like params after APACHE_ENABLE_LAYOUT, since we'd have to guess what AC_INIT is supplying as the defaults (we can test for $prefix = NONE, but that trick doesn't work everywhere). Are we content with --enable-layout potentially overwriting all --prefix -like parameters? -aaron
