Hi!  Thanks for the report.  I have reverted the recent
s/CFLAGS/AM_CFLAGS/ change for the -Wno-pointer-sign test, since it is
not needed there.

I couldn't find any other test in configure.in that set AM_CFLAGS and
then tested whether it worked or not, though.  Please test whether
tomorrow's snapshot works for you.

Regards,
Simon
