I am seeing other build errors on windows from quant.cpp - were these also
fixed in this path you're referring to, or should we open a new issue for
it?
C:\SmokeTest\Test_harness\vc10_64_multilib\default\x265-shared.vcxproj"
(default target) (13) ->
api.obj : error LNK2019: unresolved external symbol "struct x265_api
const * __cdecl x265_12bit::x265_api_get_75(int)"
(?x265_api_get_75 at x265_12bit@@YAPEBUx265_api@@H at Z) referenced in function
x265_api_get_75 [C:\SmokeTest\Test_harness\vc10_64_multilib\default\x265-
shared.vcxproj]
