Ah. I wrote OCTAVE_CONFIGURE_WARNING for configure.ac so that this
would happen (warnings at the end), but I see it's not used for this
Qscintilla warning. My intention was for all configure.ac warnings to
use OCTAVE_CONFIGURE_WARNING, but I see people went back to using
AC_MSG_WARN since last time I was messing with configure.ac.

Can we replace most usages of AC_MSG_WARN with OCTAVE_CONFIGURE_WARNING?
