OK.  I just saw that the config.log said:

"./configure: line 921: C:\Program: No such file or directory"

Which looked like windows nonsense to me. But honestly, I spent three 
days trying to compile against decklink on a stable windows 7 box.  I 
finally punted, and built a windows binary on my Debian laptop in 2 
hours. Runs fine. YMMV. You can probably download an arm x-compiler from 
the repos.

You might still need a runtime engine (RTOS) that supports POSIX 
threads.  http://www.nuttx.org/ might help.
