Okay. I have not noticed that.

Okay, great! I did not know that we were supporting other architecture
than intel for build :)

BTW, I picked up the "code" from another package. Probably took it from
wine.mk.

	# Wine needs to enable 64-bit build tools on 64-bit host
	ifeq ($(HOSTARCH),x86_64)
	HOST_WINE_CONF_OPTS += --enable-win64
	endif

I may filter to %64 instead. Do very 64bits architectures are named
using 64?
