makefile.gcc

给出了 zip 压缩算法的完整实现过程。

# Makefile for Zip, ZipCloak, ZipNote and ZipSplit for port of gcc producing
# native Win32-Intel binaries. Derived from makefile.w32.
# Currently supported implementations: Cygwin and MinGW.
# Authors: Cosmin Truta, Christian Spieler, and possibly others.
# Last updated: 2005-Mar-25.
#
# To use, do "make -f win32/makefile.gcc".

# Optional nonstandard preprocessor flags (as -DMEDIUM_MEM or -DNO_ASM)
# should be added to the environment via "set LOCAL_ZIP=-DFOO" or added
# to the declaration of LOC here:
LOC = $(LOCAL_ZIP)
