Thanks. See comments below.

Lowercase: "wine".

Indentation is not correct for this line. Also, just for curiosity,
could you give some details on the issues you've seen when building
wine against uclibc?

Does it work with the musl C library? In other words, do you need:

	depends on !BR2_TOOLCHAIN_USES_UCLIBC

or:

	depends on BR2_TOOLCHAIN_USES_GLIBC

 ?

You need to take into account the uClibc issue here, by adding
something like:

	wine needs an (e)glibc toolchain w/ IPv6, threads

Of course assuming what you need is glibc only.

Also, lowercase "wine".

Can you double check whether it's LGPLv2.1 or LGPLv2.1+ ?

Having the target wine poke directly inside the source directory of
host-wine isn't that great. Ideally, we should be able to remove the
source directory of a package immediately after it has been built. The
host wine package gets installed to $(HOST_DIR). Aren't the tools you
need also installed there? If not, then please add a comment above this
line that explains what is going on.

Your Config.in file only allows the wine package to be built on i386
and x86-64, so the aarch64 part seems superfluous here. So maybe just:

WINE_CONF_OPTS += $(if $(BR2_ARCH_IS_64),--enable-win64)

There is no package named 'x11r7' in Buildroot, so clearly this hasn't
been tested.

Did you test all those optional dependencies? If not, then please
simply disable the ones you haven't tested (i.e force --without-<foo>
in WINE_CONF_OPTS). Developers interested in enabling more optional
dependencies can do so later on.

Other than that, looks good. Do you have a pointer to a simple
command-line only Windows program that we could potentially use to test
this wine package?

Thanks,

Thomas
