# Makefile -- KPJOY.DRV, built on Linux with Open Watcom v2's 16-bit Windows
# target (the copy JoeyLib's installer sets up, unless WATCOM names another).
#
#   make            bin/kpjoy.drv
#   make LOG=1      the same, logging to C:\KPJOY.LOG (see kpjoy.c)
#   make clean      remove obj/ and bin/
#   make OBJ=DIR BIN=DIR   build somewhere else (an installer's build tree)
#
# Compiler flags: Windows target (-bt=windows) DLL (-bd), small model with
# SS != DS (-ms -zu: a driver runs on its caller's stack), Windows prolog
# for exported functions (-zw), no stack probes (-s), 286 code (-2),
# structures packed on 2 bytes as the Windows headers are (-zp2), all
# warnings, as errors (-w4 -we).
