I'm having second thoughts after review of this spreadsheet: pybind11.h v2.7.0 pragma block analysis Marking this PR as draft for now. |

Instead of poping the warning, I think the recommended way to handle this error is actually to call the _strdup on MSC: https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/strdup-wcsdup?view=msvc-160 strdup is an alias to it.

The 2nd thoughts I had when marking this PR as draft yesterday:
- Cluttering pybind11 with MSVC-specific things is ugly.
- Better to simply disable the warning on the command line?
To me it looks like just another MSVC oddity, dirt that I want to keep out of my house, to use stronger words.
But we have similar pros-and-cons for most of the 11 items that I enumerated here yesterday:
pybind11.h v2.7.0 pragma block analysis
I was thinking of suggesting a focused action meeting to go through the list and decide what to do about each one. I'll ping you and @henryiii on slack about it.

I think we should do what MSVC wants; like it or not, they are a major target for us. We should not requires any special flags to build without warnings; this is a header-only library and is not always called through build methods we control.
