# Generic Windows NT makefile
# Copyright 1995 by Andrew L. Bliss
#
# The make is controlled by several variables:
#   TARGET
#     <name>.lib - Build a lib
#     <name>.exe - Build an executable
#
#   PLATFORM
#     i386  - 80X86 build
#     mips  - MIPS RX000 build
#     alpha - DEC Alpha build
#     ppc   - PowerPC build
#
#   BUILDTYPE
#     DEBUG  - Debug build with symbols
#     RETAIL - Non-debug build, optimized, no symbols, default
#
#   WIN32INC - Full path to Win32 include files
#   WIN32LIB - Full path to Win32 libraries, minus platform
#   CRT32INC - Full path to C runtime include files
#   CRT32LIB - Full path to C runtime libraries, minus platform
#
# All tools must be on your path
