# Makefile for Zip, ZipCloak, ZipNote and ZipSplit
# using emx 0.9c for DOS.
# By Kai-Uwe Rommel, Chr. Spieler, E-Yen Tan (and others).
# Last updated 7th January 2007.
#
# This Makefile is a stripped down version of win32/Makefile.emx that
# builds executables applying the default MSDOS emx setup.  For variant
# targets (using zlib), and cross-compilation for WIN32 or OS/2, take a
# look into "win32/makefile.emx" resp. "os2/makefile.os2".
#
# Supported Make utilities:
# - Microsoft/IBM nmake (e.g. from MSC 6.0 or newer)
# - dmake 3.8 or higher
# - GNU make, at least version 3.68 (GNUish 16-bit port, RSXNT Make 3.75 in a
#   Win95/WinNT DOS box, DJGPP v1.12 Make 3.71, some versions of DJGPP v2.x
#   32-bit Make; current DJGPP v2.01 Make 3.76.1 does NOT work)
# - NOT watcom make
# The "smart" Make utilities mentioned below are Christian Spieler's
# enhanced version of GNUish 16-bit Make (3.74) and his adaption of these
# GNU Make sources to EMX (32-bit).

# Supported 32-bit C Compilers for MSDOS:
# - GNU gcc (emx kit 0.9c or newer, 32-bit)

# Supported Assemblers:
# - GNU as with GNU gcc


# To use, enter "make/nmake/dmake -f msdos/makefile.emx"
# (this makefile depends on its name being "msdos/makefile.emx").

# emx 0.9c, gcc, a.out format, for MS-DOS
