--enable-ignore-missing-data does not suppress warnings in mapserver

[woodbri]

If I configure mapserver with --enable-ignore-missing-data is does NOT suppress the warning messages. This is problematic as it fills the apache errorlog and can potentially overflow the filesystem.

  ./configure \
    --enable-ignore-missing-data \
    --enable-debug \
    --with-httpd=/usr/sbin/apache \
    --with-proj=/usr \
    --with-agg=../agg-2.4 \
    --with-gd=static,/usr/local \
    --with-freetype \
    --with-postgis \
    --without-tiff \
    --with-wmsclient \
    --with-fribidi-config=/usr/local/lib/pkgconfig/fribidi.pc
