Subject: bug#14528: remake-configure-dependencies test fails on fast systems without subsecond timestamps
Date: Sat, 1 Jun 2013 12:20:03 +0100

Automake 1.13.2 failed t/remake-configure-dependencies.sh in two
consecutive attempts on Ubuntu autobuilders.  On inspection I found that
our autobuilder network happened to pick the same backend machine each
time, which was a relatively old one still using ext3.  (Our newer
builders use ext4.)  On running this test in a loop-mounted ext3
filesystem on my laptop, I reproduced the failure first time:

  Running from installcheck: no

I think perhaps a sprinkling of $sleep is called for in this test?

Thanks,
