We override HOME in t/test-lib.sh; shouldn't this be done there?

I am puzzled. 'set up --show-origin tests' do say INCLUDE_DIR is
"$HOME/include" already, so why is this needed?

> +	export HOME INCLUDE_DIR

Existing tests use $INCLUDE_DIR (and $HOME) as shell variables just
fine without exporting.  Why do these need to be exported only on
MINGW?

Perhaps if you adjust HOME before 'set up --show-origin tests' test,
most (or all) of the above become unnecessary?

The changes below that skip tests that relies on pathnames that
cannot be used on Windows makes sense, though.
