I can't use my build script for the DWindowsProject to generate headers because it's multithreaded and HTOD works by outputting any converted .h header file to the *current directory*, e.g.:

> htod foo\bar.h

This puts the bar.d file to the *current directory*. I can't just move this newly generated .d header around because my builder is multithreaded and what ends up happening is multiple translated header files with the same name get overwritten with each other. I need -od or -of for HTOD, just like we have in DMD.

I can't use an explicit name because:

> htod foo\bar.h foo\bar.d

Here's what bar.d has in its contents:
/* Converted to D from foo\bar.h by htod */
module foo\bar;

That won't compile.
