NO ! It says "Compiled with stabs debugging format."

DONE! with the following result.



I have adapted the build script:
------------------------------------------------
...

base_dir="${PWD_DIR}"
source_dir="${base_dir}/emacs"
build_dir="${source_dir}/.build"
dest_dir="${source_dir}/.inst"

prefix_dir_name="usr/local/emacs-${rel}"
prefix_dir="/${prefix_dir_name}"

cd ${base_dir}
# echo ""
# echo "Unpacking the source..."
# tar -xjf ${PKG_DIR}/emacs-${rel}-cvs-src.tar.bz2

mkdir -p ${dest_dir} ${build_dir}

cd ${build_dir}

echo ""
echo "Configuring..."
LDFLAGS='-ggdb -gdwarf-2 -g3 -O2' \
CFLAGS='-ggdb -gdwarf-2 -g3 -O2' \
../configure --prefix=${prefix_dir}

echo ""
echo "Making the bootstrap..."
make bootstrap

make install prefix=${dest_dir}/${prefix_dir_name}

echo ""
echo "Making the binary package..."
cd ${dest_dir}

find ${prefix_dir_name} \! -type d | \ tar cjfT
${base_dir}/emacs-${rel}-cvs.tar.bz2 -
------------------------------------------------




The first thing to say is that there is an 'Abort' when 'make install...':
---------------------------------------------------------------------------
Compressing *.el ...
chmod -R a+r
/tmp/emacs/.inst/usr/local/emacs-22.0.50/share/emacs/22.0.50/leim
make[1]: Leaving directory `/tmp/emacs/.build/leim'
cd lib-src; make maybe-blessmail  \
          MAKE='make'
archlibdir='/tmp/emacs/.inst/usr/local/emacs-22.0.50/libexec/emacs/22.0.50/i686-pc-cygwin'
make[1]: Entering directory `/tmp/emacs/.build/lib-src'
../src/emacs -batch -l /tmp/emacs/lib-src/../lisp/mail/blessmail.el
Fatal error (6)make[1]: *** [blessmail] Aborted (core dumped)
make[1]: Leaving directory `/tmp/emacs/.build/lib-src'
make: *** [blessmail] Error 2

Making the binary package...
---------------------------------------------------------------------------




I have never got this until now, usually I have got:
-------------------------------------------------------
Compressing *.el ...
chmod -R a+r
/tmp/emacs/.inst/usr/local/emacs-22.0.50/share/emacs/22.0.50/leim
make[1]: Leaving directory `/tmp/emacs/.build/leim'
cd lib-src; make maybe-blessmail  \
          MAKE='make'
archlibdir='/tmp/emacs/.inst/usr/local/emacs-22.0.50/libexec/emacs/22.0.50/i686-pc-cygwin'
make[1]: Entering directory `/tmp/emacs/.build/lib-src'
../src/emacs -batch -l /tmp/emacs/lib-src/../lisp/mail/blessmail.el
Wrote /tmp/emacs/.build/lib-src/blessmail
chmod +x blessmail
Assuming /usr/spool/mail is really the mail spool directory, you should
run lib-src/blessmail
/tmp/emacs/.inst/usr/local/emacs-22.0.50/libexec/emacs/22.0.50/i686-pc-cygwin/movemail.exe
as root, to give movemail.exe appropriate permissions.
Do that after running make install.
make[1]: Leaving directory `/tmp/emacs/.build/lib-src'

Making the binary package...
-------------------------------------------------------




I have verifyed that now Emacs is 'Compiled with DWARF 2
debugging format.'

After the build was completed and the binary package result installed:
----------------------------------------------------------------------
cd /usr/local/emacs-22.0.50/bin
$ ./emacs
Fatal error (6)Aborted (core dumped)
