oh, and "invalid back reference" is a gnu regex error for \n without a matching nth group.
also, the configure.in:5: warning: do not use m4_patsubst: use patsubst or m4_bpatsubst now looks suspiciously relevant (it comes from autoconf.m4, and passes through the arguments to patsubst -- and at a *glance*, I'm not convinced it properly quotes them, though I couldn't say for sure without some test cases and more attention to the m4 manual. But because a quoting problem could lead to the back reference error, it makes me twitchy enough to look at a bit more closely... Are the sources that give these errors the current "apt-get source heimdall", or something else? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
