Commit aca31e3815b9bd9c696cf0c74cc4a80ad7e35ec9 seems to have broken
'./autogen.sh'. It's requiring me to invoke it with the 'autoconf'
parameter. A quick peek at the source looks like it should be automatic,
but I think there's a bug in the shell code. At least, I needed this
change to make the 'autoconf' automatic under bash. I don't know enough
about the differences between bash and pure POSIX shells to know if this
is correct everywhere, but it fixes the issue for me:

I meant that your patch should be fine to apply.
But AFAICS at the next merge from emacs-25 the relevant code will all
disappear anyway. Or there will be a merge conflict.

I think this problem is present only in master. I installed the attached patch, which should fix it. David, thanks for reporting it.

This shell compatibility issue isn't documented in the Autoconf manual, so I installed a patch to document it, here:
