# Makefile for UnZip, fUnZip and UnZipSFX
# for emx 0.9c / gcc under MS-DOS. Derived from makefile.os2
# By E-Yen Tan (with mods by Christian Spieler).
# Last updated 10 February 2001 (Christian Spieler).
#
# This makefile should work fine with GNU make and hopefully some others.
# Tested with GNU make 3.71 gnuish 16-bit and djgpp 32-bit versions.

# Version 5.1 of the RSX extender provides long file name support under
# Windows 95. If you don't have Windows 95 or use a version of RSX prior
# to 5.1 (or simply don't want LFN support) remove -DUSE_VFAT from CFLAGS.
# Note that if you have a version of RSX prior to 5.1, you can still compile
# with USE_VFAT enabled and upgrade RSX.EXE at a later stage.
#
# If you enable USE_VFAT then long file names under plain DOS will simply be
# truncated to 8.3 format without mapping. See doscfg.h for details.
