Thanks for the bug report. Which version of Automake are you using?
If older than v1.10b-62-g0e411a0, then please update to 1.11.1 and
retry. It may be possible that we overlooked one case in the
above-mentioned commit, but I don't see where that should be.
If the failure persists, please post short configure.ac and
Makefile.am which expose the problem for you. You can start with
what I show below, and adjust that if it doesn't expose it.
Does the failure happen reliably, i.e., every time, or only sometimes?
You can try in a loop with something like
for i in 1 2 3 4 5 6 7 8 9 10; do
rm -f axl.[clo]*
make V=1 -j1
done
Does 'make -B -jN' work for you reliably?
Which exact FreeBSD version are you using? I'm kind of suspecting a bug
in the make implementation, or we're overlooking something with
one-shell issues.
