Sorry for not getting back to this sooner, school happened.

First, why is this used rather than autoreconf?

  That just runs part of the process. does all the steps
required to setup the autotools.

As far as I can tell, tests to make sure various programs exist, sets up and runs libtoolize, and runs aclocal, autoheader, automake, and autoconf.

According to [1], "autoreconf runs autoconf, autoheader, aclocal, automake, libtoolize, and autopoint (when appropriate)". So other than setting up libtoolize, they seem to do the same things.

For example, knows the
difference between the main version of libtoolize, which have to be
handled differently.

I haven't looked at the libtoolize stuff much (nor do I have much experience with libtool), but why do they have to be handled differently? Is it just because of the way gnash is structured or is this true of all projects using libtool?

Third, is there any point to any of the following, or can they be removed?

  Those lines are testing if various macros are used in the top level script. If they are used, then that effects what happens in
generating all the proper files in the right places.

I don't understand this in the context of my mail. Lines 164-172 aren't testing if various macros are used, the test for the macros directory and setting -I macros always happens, and doesn't really affect generating the proper files, and setting conf_flags doesn't seem to do anything.

If this was a reply to the second part of my mail, which reads
Second, what is the point of the
     if grep "^AM_GLIB_GNU_GETTEXT" >/dev/null; then
on line 184 and similar on lines 190 and 194, and lines 43, 53, 63, and 72? is never changed (is it?) and those strings aren't in it, so that 
code will never run.

...then my point is that never changes outside of actual checkins, right? So unless someone is modifying the source (in which case everything is moot), the checks are useless.
