Subject: [PATCH 1/4] Add buffer around AC version check

Subsequent patches will modify this portion of the code, but
without the buffer the postgresql version and the copyright dates
become part of the context, which then interferes with
make update-package-postgresql

Subject: [PATCH 2/4] Change AC version check

See discussion in #672, originally the m4 check was removed, but
subsequently a need for it in a different form was found so the
AC_PREREQ line was added.

The m4 check was removed by @mabrand in d31b6ec92d0779da
The AC_PREREQ was added by @avih / @TimothyGu in caa19541103025

This modifies original patches by @TimothyGu, and is required
due to the loss of the enable_shared variable in newer versions
