that's some good investigation :)

it's a well known problem, and it looks like for you the *workaround* 
for the problem doesn't work, which is odd ...

the command must be this from Tempfile.mk

... however: on Windows you should be using a GNU make 4.0 or newer, 
where Tempfile.mk would use the built-in $(file) function to write.

somehow you're using make 3.81 or 3.82, which does work on unixes but 
apparently not on Windows, and since we have LODE to download a newer 
make automatically it's not worth fixing that.

i think we should check for this in configure:
