-# win16_3.11.mk -- Make configuration for Win16
-#
-# This file configures gmake to build the Win16 variant of
-# NSPR 2.0. This file has the function of two files commonly
-# used on other platforms, for example: winnt.mk and
-# winnt4.0.mk. ... The packaging is easier and there is only
-# one variant of the Win16 target.
-# 
-# Win16 is built using the Watcom C/C++ version 11.0
-# compiler. You gotta set up the compiler first. Follow the
-# directions in the manual (Ha! ... really, its not a
-# problem). The Watcom compiler depends on a few environment
-# variables; these environment variables define where the
-# compiler components are installed; they must be set before
-# running the make.
-# 
-# Notes:
-# OS_CFLAGS is the command line options for the compiler when
-#   building the .DLL object files.
-# OS_EXE_CFLAGS is the command line options for the compiler
-#   when building the .EXE object files; this is for the test
-#   programs.
-# the macro OS_CFLAGS is set to OS_EXE_CFLAGS inside of the
-#   makefile for the pr/tests directory. ... Hack.
-# 
-# USE_WATCOM_DEBUG_DATA environment variable causes the
-#   watcom compiler flag to be set to -hw (otherwise
-#   it is set to -hc (codeview debug data)) for debug builds.
