I have updated this for 16devel and registered it in the commit fest.

To summarize:

- Autoconf 2.71 has been out for 1.5 years.
- It is available in many recently updated OSs.
- It allows us to throw away several workarounds.

Also:

- The created configure appears to be a bit faster, especially in the 
cached case.
- It supports checks for C11 features, which is something we might want 
to consider in the fullness of time.

Hence:
