Hello Dave,

I've created a patch file for Autoconf fixing this problem. I've posted it to Autoconf but noone responded yet. Can you try it and let me know?

ok, i still don't completely understand where that regex comes from,
but i think it's parsing AC_CONFIG_FILES that gives the problem.

it turns out that any long AC_OUTPUT() line gives this error.

i've attached a test case.

i tried both 1.7.1 as downloaded from,
and also the 1.7.1 debian package for the "testing" distribution.

i'm trying to upgrade a project to use automake-1.7
and i'm getting the following error(s):

/tmp/am4tf8PSRs/traces.m4:822: /usr/bin/m4: Error matching regular expression 
`^ *\(.*\) *$'
Use of uninitialized value in split at /usr/local/bin/automake-1.7 line 5077, 
<GEN0> line 283.

clearly the second is caused by the first.. but where is traces.m4 coming from?
or, how can i make the tmp-dir not be deleted?

also:  what's going wrong in the first place?  that message is pretty vague...
