# Makefile for UnZip, UnZipSFX and fUnZip                       23 July 1994
#
# - for Microsoft C, version 6.00 or higher, for use under OS/2 1.x (16-bit)
# - for Watcom C/386, version 9.0 or higher, for use under OS/2 2.x (32-bit)
# - for IBM C/C++ Set/2, for use under OS/2 2.x (32-bit)
# - for Borland C++, for use under OS/2 2.x (32-bit)
# - for GNU gcc (emx kit), version 0.8e or higher, for use under OS/2 2.x
#
# cross-compilation:
# - for Microsoft C, version 6.00 or higher, for use under MS-DOS (16-bit)
# - for GNU gcc (emx), version 0.8h or higher, for use under MS-DOS (32-bit)

# To use, enter "{d,n}make -f makefile.os2" (this makefile depends on its
# name being "makefile.os2", and it must be in the main unzip directory).

# Notes on Microsoft C 6.00 compilation for OS/2:
#
#   The resulting programs can be used under OS/2 1.x or 2.x protected
#   mode only, not under DOS.  A larger stack has to be used for OS/2
#   because system calls use more stack than under DOS; 8k is recommended
#   by Microsoft.

# Notes on IBM C Set/2, Watcom C/386, Borland C++ or emx+gcc compilation:
#
#   The resulting programs can be used under protected mode of OS/2 2.x
#   only, not under OS/2 1.x and not under DOS.
#
#   The NFLAGS macro is used to work around an optimization bug in the IBM
#   C++ Set compiler; this is fixed by CSD #4, so NFLAGS="" can be used for
#   all targets below.  We'll leave it as is for this release...
#
#   For Watcom C/386, edit the os2$(OBJ) target so that os2/os2.c reads
#   os2\os2.c instead.  Watcom can't handle forward slashes; gcc can't
#   handle backslashes.  We'll see about making this a macro next time...

	@echo "   msc mscdos ibm ibmdyn ibmdebug ibmprof"
	@echo "   watcom borland gcc gccdyn gccdebug gccdos"
