The source from this directory was copied from the libtheora-1.0 source distribution using the update.sh script. The changes made were those applied by update.sh, the addition/update of Makefile.in files for the Mozilla build system and the patch in bug below. Bug 455357 - WinCE LibTheora Pre-defined Macro usage in local variable 455357_wince_local_variable_macro_clash_patch This patch is needed for building WinCE / WinMobile because the Mozilla WinCE Shunt Library currently includes windows.h header file, which causes a conflict with local variables in the oc_dering_block() function. This issue should be cleared up soon, with a reworking of the WinCE Shunt Library (Bug 456788 - reduce windows ce shunt impact). Until then, this simple patch allows WinCE to finish compiling.
