i get the expected result.

i changed configure to

#!/usr/bin/bash from #!/usr/bin/sh

this fixed the problem with finding the linker.  it doesnt really 
answer whats wrong with sh, but i can look at that seperatly later, i 
can live with this fix ;-)

no

yes this was the problem.  i had picked this up and tried building 
from command line with this and it didnt object to -o being this but 
when i setenv variable ac_cv_exeext=""  it worked fine.  so i looked 
at what is wrong with the configure script.  the following change 
needs to be made:


echo $ac_n "checking for executable suffix""... $ac_c" 1>&6
echo "configure:1181: checking for executable suffix" >&5
if eval "test \"`echo '$''{'ac_cv_exeext'+set}'`\" = set"; then
   echo $ac_n "(cached) $ac_c" 1>&6
else
   if test "$CYGWIN" = yes || test "$MINGW32" = yes; then
     ac_cv_exeext=.exe
else
   rm -f conftest*
   echo 'int main () { return 0; }' > conftest.$ac_ext
   ac_cv_exeext=
   if { (eval echo configure:1191: \"$ac_link\") 1>&5; (eval $ac_link) 2>&5;
}; then
     for file in conftest.*; do
       case $file in
       *.c | *.o | *.obj | *.xcoff ) ;;                  <==== added | *.xcoff
       *) ac_cv_exeext=`echo $file | sed -e s/conftest//` ;;
       esac
     done
   else
     { echo "configure: error: installation or configuration problem: compiler
cannot create executables." 1>&2; exit 1; }
   fi
   rm -f conftest*
  test x"${ac_cv_exeext}" = x && ac_cv_exeext=no
fi
fi

thanks!

At a recent computer software engineering course in the US, the participants
were given an awkward question to answer.  "If you had just boarded an
airliner and discovered that your team of programmers had been responsible
for the flight control software, how many of you would disembark
immediately?"
