Right. Mingw makefile based build cannot be expected to be widely used.
Autotool based offer common build process. It could be used either for 
native or for cross builds.

No it is header from mingw runtime . It is fine to define it in makefile 
based libxml mingw build.

You patch looks good to me.

Uhh may be one day winsock library will be removed from both builds - 
autotool & makefile based .

This is issue with variable export/import. May be makefile libxml build 
use incorrect header or is installed incorrect header

No idea.
May be a library or crt file is build with 'old' compiler . 4.7.x is not 
compatible with versions before .
