v4.1.1 - ImageTypes() returns nothing, phpinfo reports GIF support enabled

On the same machine (RH 6.2 x86), I can get php 4.0.6 (and earlier) to compile with gd support. phphinfo() shows the following: GD Support - enabled GD Version - between 1.3 and 1.6.1 FreeType Support - enabled FreeType Linkage - with TTF library GIF Support - enabled and ImageTypes() returns IMG_GIF using the following configure options: --disable-debug \

        --enable-track-vars \
        --with-pgsql=/usr/local/pgsql/lib \
        --with-mysql \
        --with-zlib \
        --with-mm=../mm-1.1.3 \
        --with-gd \
        --with-jpeg-dir \
        --with-ttf \
        --with-fdftk=../FDFToolkitForUNIX \
        --with-openssl \
        --with-apache=../apache_1.3.22

        --enable-track-vars \
        --with-pgsql=/usr/local/pgsql/lib \
        --with-mysql \
        --with-mm=../mm-1.1.3 \
        --with-gd \
        --enable-gd-native-ttf \
        --enable-gd-imgstrttf \
        --with-ttf \
        --with-jpeg-dir=/usr \
        --with-png-dir=/usr \

Before I do a make, I do a make clean, then rm -f config.cache config.log config.status, then re-configure. Thanks for any constructive input, Charles Dostale Sys Admin http://www.silveroaks.com chasd at silveroaks.com
