Since some time(a very little one) the build directory can be distinct from= =20 the source one; wouldn't this feature be fine for this purpose, with two=20 different build dirs? > Any change to an existing source file in one tree will > affect the other tree too. For users(Ingo knows this, obviously): note that this is not true with patc= h:=20 when you patch one tree, the other tree remains unpatched. This happens sin= ce=20 patch doesn't modify a file, but replaces it with another file(which is no = more an hard link) containing the new version. Bye --=20 cat <
