Dmitry Timoshkov (@dmitry) commented about dlls/kernel32/kernel32.spec:
@ stdcall CopyLZFile(long long) LZCopy @ stdcall CreateActCtxA(ptr) @ stdcall -import CreateActCtxW(ptr) -# @ stub CreateBoundaryDescriptorA +@ stdcall CreateBoundaryDescriptorA(str long) @ stdcall -import CreateBoundaryDescriptorW(wstr long)
Probably the stub should be added to kernelbase instead, and imported to kernel32 like for the W variant.
