unedit timestamp

[Dominic Williams]

Problem:

1) I "cvs edit" a source file.
2) I modify it.
3) I re-build the project (make detects the file is newly modified).
4) I "cvs unedit" the file.
5) I call make: no recompile, because cvs replaced the modified file 
with a backup of the original, with the original timestamp, which is 
now older than the recompiled project...

I know I can use touch or make -a, but is there a solution on the CVS 
side ?

Thanks.
