Out of curiosity: how fast is this machine, how many and what kind of

Could you please show the time stamps when the failure happens. Like
this (in the tests subdirectory of the build tree):
$ while make check VERBOSE=x TESTS=acloca20.test; do :; done
$ ls -lart --time-style=full-iso testSubDir testSubDir/autom4te.cache
My assumption is that the second run of autoconf happens within the same
second as the first; if that is true, then the patch below should fix
this. Could you try it?
Thanks,
Ralf
* tests/acloca20.test: Use `--force' with the second $AUTOCONF,
to force update on fast machines where both autoconf invocations
happen within the same second.
