'win32/*.bat' do not handle SRCROOT long path names with spaces correctly
as an example, from a DOS box, type:
set SRCROOT=c:\Xiph CVS\
call build_vorbis_static.bat
produces the error:
cvs==. was unexpected at this time.
and does *not* set %SRCROOT% to any value
resolution:
replace the line:
if .%SRCROOT%==. set SRCROOT=c:\src
with the line:
if ".%SRCROOT%"=="." set SRCROOT=c:\src
