                 Summary: Running autoscan in a directory with ltmain.sh

Details:

Let's say that, in an empty directory, I have a configure.ac file that looks
like this:

AC_INIT([testcase])
LT_INIT
AC_OUTPUT

Then I autoreconf, which puts ltmain.sh into the current directory. Now when I
run autoscan, it produces the following warnings:

Local-Admins-MacBook-Pro:autoconf_bug_reports_dir localadmin$ autoscan
configure.ac: warning: missing AC_PROG_CXX wanted by: ltmain.sh:960
configure.ac: warning: missing AC_PROG_INSTALL wanted by: ltmain.sh:1028
configure.ac: warning: missing AC_PROG_MAKE_SET wanted by: ltmain.sh:2163
configure.ac: warning: missing AC_PROG_RANLIB wanted by: ltmain.sh:2455

So I add these macros to my configure.ac, and now, when I autoreconf again, it
includes this warning:

glibtoolize: `AC_PROG_RANLIB' is rendered obsolete by `LT_INIT'

If I then go and remove AC_PROG_RANLIB, autoscan will then warn about it being
missing again the next time I run it, leading to an endless cycle of
conflicting warnings. Perhaps autoscan could be modified to just ignore
ltmain.sh when scanning?
