wait - I was kindly provided conversion code by someone because I haven't done
COM programming in 20+ years and this is complicated stuff.
however - it is not compilable by mingw-w64 because there is no
Windowscodecs.lib or equivalent libwincodecs.a in - am I missing something? did
it get renamed? there are a bunch of others I need to include.

http://msdn.microsoft.com/en-us/library/windows/desktop/ee690307%28v=vs.85%29.aspx
I don't remember if there was anything I needed to do with the associated IDL
file(s).
well, they basically all boil down to libwindowscodec.a missing.
side comment:
not only does auto 20110812 seem stable, so also does auto 20111214 (at least
compiles iostreams without errors), would would be the latest version available
which seems to work well.
