给出了 zip 压缩算法的完整实现过程。

# WMAKE makefile for Windows 95 and Windows NT (Intel only)
# using Watcom C/C++ v10.5+, by Paul Kienitz, last revised 22 Feb 05.
# Makes Zip.exe, ZipNote.exe, ZipCloak.exe, and ZipSplit.exe.
#
# Invoke from Zip source dir with "WMAKE -F WIN32\MAKEFILE.WAT [targets]"
# To build with debug info use "WMAKE DEBUG=1 ..."
# To build without any assembly modules use "WMAKE NOASM=1 ..."
#
# Other options to be fed to the compiler can be specified in an environment
# variable called LOCAL_ZIP.  One possibility "-DDYN_ALLOC", but currently
# this is not supported unless NOASM is also used.

# We maintain multiple sets of object files in different directories so that
# we can compile msdos, dos/4gw, and win32 versions of Zip without their
# object files interacting.  The following var must be a directory name
# ending with a backslash.  All object file names must include this macro
# at the beginning, for example "$(O)foo.obj".
