Hi, Arpi!
Sometime (on Monday, November 4 at 19:21) I've received something...

I think we can just test for this flag in configure script. For example,
I have these lines in my own project:
--- acinclude.m4 ---
AC_DEFUN(AC_CHECK_LDFLAG,
[
$3=no
echo 'int main(){return 0;}' > conftest.c
if test -z "$1 $2 -o conftest conftest.c 2>&1"; then
$3=yes
else
$3=no
fi
rm -f conftest*
])
--------------------
--- configure.in ---
AC_CACHE_CHECK([for '-Wall' option], fe_cv_add_wall,
[AC_CHECK_LDFLAG("$CC", "-Wall", fe_cv_add_wall)
])
if test "$fe_cv_add_wall" = yes; then CFLAGS="-Wall ${CFLAGS}"; fi
--------------------
With best wishes.
Andriy.
