hardcoded path to vorbis source dir might be a bad idea
several of 'win32/*.bat' contain lines similar to:
set INCLUDE=%INCLUDE%;%SRCROOT%\ogg\include;c:\src\vorbis\include
set LIB=%LIB%;%SRCROOT%\ogg\win32\Dynamic_Debug;%SRCROOT%\vorbis\win32
\Dynamic_Debug
where the 'set LIB' seems to be ok, but the 'set INCLUDE' could be written
better as:
set INCLUDE=%INCLUDE%;%SRCROOT%\ogg\include;%SRCROOT%\vorbis\include
