Hello guys...

Thanks for the work!

LIBPNG:

On my (aging) x86_64 Linux system, ./configure still detects libpng 1.4
instead of version 1.5. This is strange, because, as far as I can see,
everything is correctly configured:

$ pkg-config --modversion --cflags --libs libpng
1.5.1
-I/usr/include/libpng15  -lpng15  

Though earlier versions of Povray had problems compiling with 1.5, the
latest RCs didn't. So I had to modify configure.ac, run bootstrap. It
seems configure is rather strict in _not_ finding 1.5:

AX_CHECK_LIB([png], [$required_libpng_version], [png14 png png12 png],
[png_get_libpng_ver], [png.h], [png_get_libpng_ver(NULL)], [$with_libpng])

Maybe it's time to add png15 there? Or rely on pkg-config?


STRANGE -L/usr/lib inclusion:

Near the end of compilation, I get:

g++  -pipe -Wno-multichar -Wno-write-strings -fno-enforce-eh-specs -s -O3 -ffast-math

RC5 didn't show this... I haven't found the reason yet.
