Thanks.  A -O3 build succeeds here and can be run with minor glitches
(incidentally involving cursor and tooltip frames).  A

CFLAGS='-O0 -g3 -no-pie' ../configure --with-pgtk --without-x --with-cairo 
--with-modules --with-gif=ifavailable --with-tiff=ifavailable --with-gnutls=no 
--without-pop --enable-gcc-warnings=warn-only --enable-checking='yes,glyphs' 
--enable-check-lisp-object-type=yes

build currently fails thusly
