IIUC it will cause a full rebuild for any re-run of configure, no matter now innocuous. FWIW Automake implements a solution to the "deleted header file" problem, just to deal with situations like this. In particular it arranges to emit a dummy "whatever.h:" target for any referenced header. This allows dependencies to work without breaking the build if the header is changed. GCC's "-MP" option is used for this when available. I hope that's relevant :), as I'm not 100% sure this was the problem that lead to this particular patch. If not, is there some other way to fix the problem, whatever it was? thanks, Tom
