Hi Ralf,

I had misinterpreted the cause for this problem, and thus at first couldn't
create a test case showing this behaviour.

The problem occurs when configure.ac contains a "computed m4_sinclude". The
attached small shell script creates and exercised a test case.

In order to further simplify things I replaced m4_sinclude by m4_include and
suddenly saw the root of the problem, because then aclocal complained about
a missing file "File".  It seems that (with m4_sinclude) aclocal doesn't see
the included file and consequently has no reason to update aclocal.m4.

Didn't we discuss a somewhat similar problem (aclocal mishandling included
files) a few years back?
