About the patch I posted:

printed out the message that AC_C_CHAR_UNSIGNED is probably no longer

The problem is that when the functionality is needed, then it is needed. It is not like those systems using signed characters (eg Tru64 on Alpha I think) vaporized from the face of the earth. Removing AC_C_CHAR_UNSIGNED then requires a change to the application code. It is not uncommon that the configure script is independently updated from the application and if someone actually follows this advice, then there may be silent breakage. In fact, it is becoming more and more common for the autotools part of the project to be maintained by someone who does not know anything about the internal implementation of the application.
