# Windows target, for hosts without MSVC 1.52 (the makefile, for NMAKE, is

# Compiler flags, as the MSVC build's: Windows target (-bt=windows) DLL
|
|
# (-bd), small model with SS != DS (-ms -zu), Windows prolog for exported
|
|
# functions (-zw), no stack probes (-s), 286 code (-2), structures packed
|
|
# on 2 bytes (-zp2), all warnings (-w4). The _asm blocks set variables
|
|
# Watcom cannot see set (W200), so those warnings are off (-wcd=200);
