Removed WINAPI declaration to prevent @ decoration of function name

[kshalnev]

Hello. I've got linking error "LNK2001 unresolver external symbol" while linking libeay32.lib,
which were build for UWP, namely these function were not found:
error LNK2001: unresolved external symbol FlushConsoleInputBuffer@
error LNK2001: unresolved external symbol GetProcessWindowStation@
error LNK2001: unresolved external symbol GetUserObjectInformationW@
error LNK2001: unresolved external symbol GetVersionEx@
error LNK2001: unresolved external symbol GlobalMemoryStatus@
These functions are declared in ms\winrt.cpp and only these functions have WINAPI specification
(+ GetStdHandle, but under STD_ERROR_HANDLE define), all other Win Api stubs are declared without WINAPI specification (see the file). This WINAPI declaration forces compiler to decorate name with '@', therefore functions cannot be found.
Without WINAPI declaration everything is OK.

Hi @kshalnev

I think that the issue is actually the same as issue #42. I'm pushing out a fix for this. Can you please try it again?

Sorry for the inconvenience.
