My fault. I didn't test whether QFile::open/close would update the timestamp. 
It doesn't, but it seemed it did when I tested it.

The real fix is to make <target>_automoc.cpp.files newer than 
<target>_automoc.cpp. AFAICT the only sensible way to do that is to use 
utime(2) which is part of POSIX.1-2001. and therefore hopefully portable to 
all platforms automoc is supposed to run on.

I committed to kdesupport. When you still have problems then it's because 
automoc4 doesn't get run and doesn't get a chance to update the .files 
timestamp. In that case either do a make clean or simply a "touch 
**/*_automoc.cpp.files"
