STAPI compilation issue

After the 3rd party license signed, I got the 27Sep07_M6_DVBT_71xxlinuxref.tar.gz, which included the stapi code and testapp code. When I tried to compile the stapi kernel module and test application. I found the testapp could not pass the compilation, the symbol,STEVT_RegisterDeviceEvent, was missing. So I took a look into it. And found something strange. In the package, the time stamp of the .c file is later than the .o file, like ./src/stevt/linux/stevt_ioctl/stevt_ioctl_lib.c and .o. The symbols in the .o file could not be found in .c file.

Looking into the old libstapi_stapi4.a, there is no symbol like STEVT_RegisterDeviceEventInt. But in my compiled libstapi_stapi4.a, there has this symbole. Other modules has reference to this new symbol and old symbol of STEVT_RegisterDeviceEvent, but the old one was gone.

It seems the source of package was patched. And the STEVT module was changed, but not the only one.

Could anybody to see what goes wrong?

Thanks.
