When you say you couldn't compile, what did the failure look like?

I don't think the extra-cmds are needed in AC_OUTPUT. If you look at the 
generated config.status file, the last command is:

test -z "$CONFIG_HEADERS" || echo timestamp > src/stamp-h

When you spec the extra-cmds, they just go after this and do essentially 
the same thing.

The failure I was seeing was that autoheader was run without specifying
the config dir, thus it couldn't find the acconfig.h file and a few things
where'd added to the config.h file (namely defining UNSIGNED_8_BIT_T and
friends). I beleive the real solution is to just move acconfig.h into the
top level directory and remove the '--localdir=config' from the bootstrap
script.

I just verified that this indeed solves the failure I'm seeing. Here's a 
sample of the failure output:

I was seeing this failure occur when I issued a make from within the src 
dir after changing the configure.in file and running bootstrap but not 
running configure again.
