This seems like a very annoying optimization. IIUC, that means if I'd 
touch the timestamp of 'configure.ac' without changing its content, I'd 
end up in this hole of 'configure.ac' being newer than 'configure' but 
'configure' not being updated. That doesn't seem to be the case in one 
of my projects. If I just 'touch configure.ac && make' all downstream 
files are updated as expected (except 'config.h', which is a known 
behavior), so I suspect you have something else going with the 
dependencies. Impossible to guess what without seeing the relevant 
Makefile snippet.

Cheers,

Peter
