Export internal function

[FrankXie05]

Hello, I am the maintainer of vcpkg.
When updating the Vc version to 1.4.3, the CI test reported an error about the vc's support for triplet x64-uwp.
The reason may be the incorrect use of internal functions. I made a patch using the original definition of the function.
Expectation: Want to request upstream confirmation if it will affect the overall code structure and function usage.

Hi! Thank you so much for taking the time to find the cause for the build failure. I opened a PR to include your patch: #347.
