Yes, of course I read that, but I find it rather strange to remove all the
makefiles by an advanced automatic "autoconf/automake" system, and then
every user except for Debian Linux (which I doubt is the majority of
non-windows users) has to edit the file by hand before even bootstrap
runs. 

How about a wrapper (as -like google told me- e.g. Quakeforge does) that
checks for both and uses whichever is better? 

#!/bin/sh
# detect autoconf 
# Quakeforge showed how to do it.
#
AUTOCONF=`which autoconf2.50 2> /dev/null`
if [ -x "$AUTOCONF" ]; then
        rm -f configure.in
else
		AUTOCONF=`which autoconf 2> /dev/null`
        if [ -x "$AUTOCONF" ]; then
		AC_VER=`autoconf --version | head -1 | sed
's/^[^0-9]*//i'`
                AC_MAJORVER=`echo $AC_VER | cut -f1 -d'.'`
                AC_MINORVER=`echo $AC_VER | cut -f2 -d'.'`

                if [ "$AC_MAJORVER" -lt "2" ]; then
                        echo bootstrap.sh needs autoconf 2.50 or greater.
                        exit 1
                fi

                if [ "$AC_MINORVER" -lt "50" ]; then
                        echo bootstrap.sh needs autoconf 2.50 or greater.
                        exit 1
                fi
        else
                echo "autoconf wasn't found at all."
		echo "bootstrap.sh needs autoconf 2.50 or greater."
                exit 1
        fi
fi
