Follow-up Comment #7, bug #41854 (project avrdude):

> support is present. Is that correct?
Nope, usb_libusb.c (which wraps USB access for the Atmel tools)
requires just USB_LIBUSB (i.e., libusb-0.1) support to be
present. The reasons are:
* libusb-0.1 API is more universally available; last I've heard, OpenSolaris
(or its successors) don't have the libusb-1.0 API at all
* except for more work rewriting our implementation ;), we wouldn't gain much
by switching the API
* all libusb-1.0 implementations known do offer a 0.1 API compatibility
wrapper anyway
So the latter is where you'd have to look for on MinGW32.
All I can tell you is that I'm using MinGW32-Crosstools under
FreeBSD to build the "official" Win32 binaries, and it works
there.
DFU support (which is the layer below FLIP) also uses the
libusb-0.1 API.
As Hannes already mentioned, pthreads are by now only used by
the FT245 implementation (low-level bitbang using FTDI FT245
chips).
