Thanks and a question or two

[John Stebbins]

I recently successfully ported my application using these tools. It sure 
made things easier.  If you curious, the project is currently at 
hbfork.googlecode.com

There were a couple packages that I had issues with.
Your version of mingw32-w32api is too old to build ffmpeg with.  Ffmpeg 
requires 3.13 or better.
There is no mingw32-pkgconfig, so configure would use the system 
pkg-config and use regular system include and library paths and flags.
I found what I needed to fix these issues here:  
http://sourceforge.net/project/showfiles.php?group_id=204414
Is this project associated with your effort at all?

This may not be your area of concern, but MinGw has problems with large 
file support.  They've had a ticket open for it since 2006 and a few 
patches have been floating around, but no resolution.  I had to patch 
several things to accommodate.
 
FYI, the repository liked to from here is currently down:
