# Makefile for gawk (GNU awk)                                   17 Sep 1993
#
# - for GNU gcc (emx 0.8g kit) [executables for OS/2 2.x or DOS (32-bit)]
# - for Microsoft C 6.00A      [executables for OS/2 or MSDOS (16-bit)]
# - for Microsoft C 5.1        [executable for OS/2 or DOS (16-bit)]

# To use, enter "make -f Makefile.os2" (this makefile depends on its
# name being "Makefile.os2").
#
# Tested with dmake 3.8 and GNU make 3.68 under OS/2

default:
	@echo "Enter $(MAKE) -f Makefile.os2 target                     "
	@echo " where 'target' is chosen from                          " 
	@echo "   msc      OS/2 exe [Microsoft C 6.00a]                "
	@echo "   mscbnd   OS/2 and DOS exe [Microsoft C 6.00a]        "
	@echo "   mscdos   DOS exe [Microsoft C 6.00a]                 "
	@echo "   msc51bnd OS/2 and DOS exe [Microsoft C 5.1]          "
	@echo "   emx      OS/2 32-bit exe [EMX/gcc; uses emxlibc.dll] "
	@echo "   emxbnd   OS/2 and DOS 32-bit exe [EMX/gcc]           "


# stdargv, glob, and director are from Stewartson's sh. These provide
# globbing and enhanced argument-passing. MSC setargv.obj is a 
# more limited alternative (and it will permit a bound version).

#STDARGV = stdargv.obj glob.obj director.obj 
STDARGV = setargv.obj
