dostsrcflags = -zu -s -g=RES_GROUP -nd=RES -nt=RES_TEXT -nc=RES_CODE

w16cflags = -bt=windows -bd -mc -zu -s -6 -oi -w3 -wcd=202
# -bd to build DLL
# -mc to use compact memory model (far data pointers, ss != ds in a DLL)
# -zu for DLL calling convention (ss != ds)
# -s to disable stack checks, since the runtime uses MessageBox() to abort (which we can't call from mouse.drv)
