canadian build for mingw host: patch for gettext 0.19.8.1

[Alexey Neyman]

[CC crossgcc list]

Hi Titus,

First off, please send the emails the crossgcc mailing list, not to me 
personally - I may not be the only person interested in a certain patch, 
etc.

asprintf is more or less common function now.

Can you describe how you set up the mingw host? I'd like to add it to 
our docs and add that to our testing regimen.

As to the patch itself, what was the problem with using asprintf from 
mingw's libraries? A build log fragment would be helpful.

It is needed to enable localization in the toolchain components. I 
haven't tested that area much myself, though.

And, I think you got it exactly the other way. gettext is not *needed* 
by glibc, it is *a part of glibc*. We only build it for *non-glibc* 
hosts/targets.

Hint: not all our supported hosts are glibc-based. If you look at the 
build script, you'll notice that gettext is skipped if the host is 
*-linux-gnu*.
