Really.

It's not "the error", it's "the errors".  Building Emacs 25 to 29 with the 
simplest possible configuration (--without-all --without-x) fails, and 
fails early on (while compiling dispnew.c), but the error messages are 
different in each case.  I attach those of Emacs 25.

That would have mattered only if the compiler had produced a non-working 
build.  It cannot even create the first object file.
