No they doesn't!
I have added "echo timestamp > ${srcdir}/src/stamp-h.in 2> /dev/null", which
will create the stamp-h.in file in the real src directory. If you run configure
from an other build directory it is needed.

This might be a solution. But I didn't like to change this, to get it easier
approved by you:-)

I had an other error output. The reason was, that UNSIGNED_8_BIT_T
and friends was not declared.

I have done (in an other build dir) configure and make. The make has
regenerated the config.h file (AFAIR), which was wrong, because of the
missing --localdir parameter to automake.

It's now 1:56 o'clock, my wife is crying -> good night!
