Glenn Randers-Pehrson 58c4f6b355 Added -DPNG_CONFIGURE_LIBPNG to the makefile CFLAGS
to prevent warnings about direct access to png structs by libpng functions
while building libpng.  They need to be tested, especially
those using compilers other than gcc.

# If you have libjpeg, you probably already have ansi2knr.c in the jpeg
# source distribution.

# If you're going to install into a temporary location
