+# Makefile for zlib
+# Borland C++   
+
+# This version of the zlib makefile was adapted by Chris Young for use
+# with Borland C 4.5x with the Dos Power Pack for a 32-bit protected mode
+# flat memory model.  It was created for use with POV-Ray ray tracer and
+# you may choose to edit the CFLAGS to suit your needs but the
+# switches -WX and -DMSDOS are required.
+# -- Chris Young 76702.1655@compuserve.com

+# Makefile for zlib
+# Watcom 10a
+
+# This version of the zlib makefile was adapted by Chris Young for use
+# with Watcom 10a 32-bit protected mode flat memory model.  It was created 
+# for use with POV-Ray ray tracer and you may choose to edit the CFLAGS to 
+# suit your needs but the -DMSDOS is required.
+# -- Chris Young 76702.1655@compuserve.com

+# To use, do "wmake -f makefile.wat"
+
+# See zconf.h for details about the memory requirements.
