[issue46405] Warning compiling main on Windows

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

Sometime between Jan 7 and Jan 16 (today) this VC compile warning appeared (debug build).
"specialize.c
..\Python\specialize.c(1243): warning C4018: '<': signed/unsigned mismatch [f:\dev\3x\PCbuild\_freeze_module.vcxproj]"
Same is repeated at end of compile.

Could and should such warnings be treated as errors in CI Windows' build?  Or is it specific to debug build?
