thanks.

/usr/bin/aclocal:

# Set the PATH appropriately
if [ "x${VER_MIN}" != "x" ] ; then
  if (( ${VER_MIN} <= 13 )) ; then
    if [ ! -x ${AUTO_STABLE}/bin/aclocal ] ; then

VER_MIN is, apparently, "57 2"
this is because the input file has several AC_PREREQ forms.

the warnings are generated by system files outside of my control.
(maybe that's because cygwin comes with both 1.4 and 1.8?)

my configure.ac is a temporary file generated from many individual
configure.in files in sub-packages:

CONFIGURES = src/configure                                               \

        egrep '(AC_INIT|AC_PREREQ)' src/configure.in > configure.ac
        cat $(addsuffix .in,$(CONFIGURES)) | egrep -v

        echo AC_OUTPUT >> configure.ac
        aclocal -I `pwd`/src/m4 --output=src/autoconf/aclocal.m4
        $(RM) configure.ac

thanks for your help.
