Hi again,
I am looking at the flex check in configure.in again. If flex is not present, or is not version 2.5.4 then you may get your environment dumped to stdout while running configure. This is due to the set command being run with no arguments.
Although non-fatal - it certainly is ugly.
Part of the problem with flex versions is that they are not consistant :-p
I took a crack at a fix, but am uncomfortable making the change as I don't really have the history on this one. If some of you out there would be so kind as to point out any flaws in my reasoning, I would apreciate it. (For example, there is a grep for the line containing 'version' that I don't seem to need with the 3 versions of flex I checked).
If one of you config wizards wants to make the change - be my guest.

here is what the current test looks like:
set `echo "" | $LEX -V -v --version 2>/dev/null | grep 'version' | cut -d ' ' -f
3 | sed -e 's/\./ /g' | sed -e 's/[^0-9 ]//g'`
if test "${1}" != "2" -o "${2}" != "5" -o "${3}" -lt "4"; then
AC_MSG_WARN(You will need flex 2.5.4 or later if you want to regenerate
Zend/PHP lexical parsers.)
fi
I am proposing:
flexvers=`echo "" | $LEX -V -v --version 2>/dev/null | sed -e 's/^.* //' -e 's/\
./ /g'`
if test ! -z "$flexvers"; then
set $flexvers
if test "${1}" != "2" -o "${2}" != "5" -o "${3}" -lt "4"; then
AC_MSG_WARN(You will need flex 2.5.4 or later if you want to regenerate
Zend/PHP lexical parsers.)
