Hello,

beside I'm interested into how to solve that problem (what is IMHO=20
off-topic on that list) this message main intention is a bug report to=20
improve the output of a configure script.

I have this two errors (?) running "configure". It is unclear what they=20
are mean. Even if I look into the "configure" script the meaning is=20
unclear to me.

     ./configure: line 5063: gl_PROG_CC_C99: command not found
     ./configure: line 5196: gl_EARLY: command not found

Please improve the output of the script to make it easier to understand=20
it for the users, to prevent further support questions and lower the=20
workload for emacs "support channels".

To reproduce:

I cloned from git and switch to "emacs-29" branch. The machine is a=20
Raspberry Pi4 with Debian 11 (pure Debian, not rasbian).

Because the configure script is missing (bug-report exists) I checked=20
the content of "configure.ac". It points out to use "autoconf" to=20
generate such a script. I did.

$ autoconf
configure.ac:55: error: possibly undefined macro: AS_ECHO
       If this token and others are legitimate, please use=20
m4_pattern_allow.
       See the Autoconf documentation.
configure.ac:1777: error: possibly undefined macro: m4_default

Two errors are there. I don't understand. But a "./configure" was=20
created. So I tried.
