Why do you cite my message above?  Is your problem related to what I
wrote, and if so, how?

What did you do since the last time this worked for you?  Line 70 of
configure.ac, and several dozen lines around it, didn't change since
last August, so something else must have happened to cause this.

AS_ECHO is defined by m4sh.m4, which is part of the MSYS Autoconf
package you find on the ezwinports site.  Are you using that package?
Do you have that file in share/autoconf/m4sugar/ in your MSYS
installation?

These are because of the missing pkg.m4 file, I think.  See my advice
to Juanma earlier in this thread.
