# see scripts/pnglibconf.mak for more options
# to support watcom calling conventions it is necessary to set PNG_API_RULE to 2
# in pnglibconf.h - copy scripts/pnglibconf.h.prebuilt, delete the first line and change
# the definition of PNG_API_RULE from 0 to 2.
#
# If you know how to do this with the Watcom build system please supply a patch
# for this makefile to the PNG implementation list.
