# Makefile for gawk (GNU awk)                                      Dec 2010
#
# - for GNU C (djgpp)         [32bit protected-mode executable for DOS]
# - for GNU C (emx)           [32bit executable for OS/2 or DOS or Windows32]
# - for GNU C (mingw32)	      [Windows32 executable for Windows 9x/NT/2K/XP/7]

# Tested with GNU make on Windows, OS/2 and DOS.
