#3762 closed defect (fixed)

mapimageio.c contains a call to deprecated (and in libpng-1.4.0 removed) function png_check_sig

Description

png_check_sig is deprecated since libpng 0.9, and removed in libpng 1.4.0 so that mapserver can't be built against libpng 1.4.0.

The suggested alternative function is png_sig_cmp.

The attached patch (against r11298) updates mapimageio.c to use png_sig_cmp instead of png_check_sig. After applying this patch, mapserver builds fine with libpng 1.4.0
