What is the failure?  I don't get any failures.  I do see the output
here, but they are are just notes / warnings.  Everything still works.

If you see failures while compiling, please provide those messages.

I don't want to do that.

These are because of older autoconf macros in some of the older m4
files we use for older imported code like glob, fnmatch, etc.  They do
still work, for now.

I haven't worked out how to import the newest versions of glob and
fnmatch while still supporting alternative OS's like Windows and VMS. 
The current gnulib implementations of these are riddled with advanced
requirements in both autoconf and automake and the resulting makefiles
which makes them unusable unless you have a full POSIX shell and utils,
including an existing implementation of make.

So for now I'm ignoring this.
