No I don't.

That's because all code is position independent in Windows.

The problem seems to be that I was writing tabs but since I have set up my
editor to show them as 2 spaces I couldn't see what was wrong.

That is the file libgccjit.dll.a

It is the import library for gccjit. It is part of the way Windows handles
dynamic libraries.

I just couldn't get Make to generate jit-w32.o from jit-w32.cc.
It looks for jit-w32.c.

I had to leave it with the .c extension.

I changed the code to generate a directory than can only be accessed by the
current user.

I've attached a new version. It contains a rewrite of the code that creates
temporary directories.
