It can very well be a real bug in 2.50, your feedback is essential.
I've just found one such bug:

/tmp % cat configure.in                                          nostromo 21:00
define([active], [ACTIVE])
AC_INIT
AC_EGREP_CPP([active], [active [active]])

/tmp % autoconf                                                  nostromo 21:01
/tmp % grep -i active configure                                  nostromo 21:01
active [active]
  egrep "ACTIVE" >/dev/null 2>&1; then

/tmp % ace                                                       nostromo 21:01
/tmp % grep -i active configure                                  nostromo 21:01
active [active]
  egrep "active" >/dev/null 2>&1; then


The real good output should be

ACTIVE active
  egrep "ACTIVE" >/dev/null 2>&1; then

but in order to keep backward compatibility, 2.50 should probably just
stick to what 2.13 said.

Pavel, Alexandre, what shall we do?
