Compiling avrdude with MinGW/MSYS

It looks like Cygwin is not a recommended build environment for arvdude (see bug #29263) anymore, so in order to build avrdude for Windows you should use MinGW/MSYS. Surprisingly this is quite simple:

download MinGW (I've used automated installer mingw-get-inst-20110316.exe),
install MinGW, required components are C Compiler and MSYS Basic System (109 MB total), preferably to default directory (no spaces in name),
download binary release of libusb-win32 (in my case libusb-win32-bin-1.2.3.0.zip),

copy from libusb package:

include\usb.h    -> C:\MinGW\include\
lib\gcc\libusb.a -> C:\MinGW\lib\
bin\x86\libusb0_x86.dll (or other depending on your OS) -> C:\MinGW\bin\

start MinGW shell (shortcut created at Programs menu or C:\MinGW\msys\1.0\msys.bat), it will create home directory C:\MinGW\msys\1.0\home\[username],
extract avrdude sources (avrdude-5.10.tar.gz in my case) to your home\[username] directory,
type (and hit enter):
```
cd avrdude-5.10
```
type:
```
./configure
```
type:
```
make
```
avrdude.exe should be created in the avrdude sources directory, with libusb support it has 847 kB in my case,
optionally reduce avrdude binary size by stripping debug symbols, type:
```
strip avrdude.exe
```
for testing connect programmer and target board (usbasp + ATmega8 board in my case, command will be different for other programmer/MCU) and to read device signature type:
```
avrdude -c usbasp -p m8
```

Resulting binary: avrdude.zip.

Note: downloading and installing libusb is optional, if you are going to use only i.e. STK-200 programmer you can skip it. It is required to use avrdude with usbasp.

Changes for avrdude 5.11 and MinGW/MSYS 20110802

it looks like bison/yacc was not installed when choosing "MSYS Basic System" in MinGW installer; install MinGW with "MinGW Developer Toolkit" component option checked,
it seems that avrdude 5.11 is not yet compatible with libusb-win32 1.2.5 (although this is only header name mismatch usb.h (expected) and lusb0_usb.h (libusb 1.2.5) most likely); use libusb-win32 1.2.4 or older.

Resulting binary: avrdude-5.11-w32-libusb.zip (no libftdi).

You can find build with libftdi at AVR Freaks Forum, savannah.gnu.org.
