Date: 9 April 2001

To apply this patch, in the Allegro directory type:

    patch -p1 < grabber-png.diff

Then you must edit your makefile and make it link with libpng and loadpng
libraries.  For example, under Linux you would find the "LIBS = " line and tack
onto the end:

    LIBS = ... -lpng -lldpng

Finally, type "make" and everything should compile.  Of course, you need libpng
and loadpng libraries installed.
