The log file for up-to-date target is attached.  The reason
for rebuild is on line 19 - 'no old signature for "hello.h"' -
as a result aap builds hello.c.aap and hello.o.  The sign
file in BDIR actually contains checksum for hello.h. 

When I set DEFAULTCHECK=c_md5, aap behaved as expected and it
recognized hello.c.aap as up-to-date.  I am attaching that logfile as
well.

I don't know how to split it up more.  I tried to show a minimum example
of the problem and there is just one source file and one header.  In
fact, the same problem occurs if I move the header code into the c-file.

Hope this helps,
