According to the autoconf manual, this is OK, but 1.4.13 or newer
would be better. I recommend installing a new version.

The `autoconf' script, which is a wrapper for `autom4te' (written in
Perl), which in turn is a wrapper around the `m4' preprocessor.

No. The git archive only contains `configure.raw', which gets
converted to `configure.ac' by FreeType's top-level `autogen.sh'
script. This `configure.ac' is in turn a template file for the
`autoconf' program that expands m4 macros like AC_INIT together with
adding more code to create a valid shell script.

No. But everything starting with `AC_' should be replaced with valid
shell script code. BTW, m4 arguments are normally enclosed in
brackets.

I don't know. :-)
I still recommend to install the newest versions of the autotools (and
m4). Doing so all necessary prerequisites are checked, which could
unveil problems not easily noticed otherwise.
