> Dear sirs,

> While trying to use autoconf-2.13 on our cross-compiler

> The problem we have is that we generate side-by-side
> with a non-suffixed executable both a map file suffixed
> ".map" and a debugger symbol table suffixed ".xdb"; then
> AC_EXEEXT says the executables are suffixed by ".xdb" if we
> configure with CC="sxc -g" (sxc is our cross compiler) and
> ".map" if we configure with CC=sxc :-(
>
> I then propose the following patch that in this case
> (if the compiler creates a file without any suffix) consider
> the executable is the un-suffixed file. We purposely do not
> check for executable as it seems that "test -x" is not so
> portable and because a cross-compiler has no interest in

read -f here please, this was an old version for the patch I sent by
error :-)
The right patch is below and is as was explained in the message;
that's what
happens when you click too fast ;-(
> ! for file in conftest.*; do
> ! case $file in
> ! *.c | *.o | *.obj) ;;
> ! *) ac_cv_exeext=`echo $file | sed -e s/conftest//` ;;
> ! esac
> ! done
> ! fi
> else
> AC_MSG_ERROR([installation or configuration problem:
> compiler cannot create executables.])

> Hope this could make its way in the next release (I do not
> like too much to have to maintain patched versions of tools locally).
