-------------------------------
I will make a PR for this hopefully over the weekend, for now just making the
ticket
> Thrift headers raise compiler warnings on MSVC
> ----------------------------------------------
>
> Key: THRIFT-5790
> URL: https://issues.apache.org/jira/browse/THRIFT-5790
> Project: Thrift
> Issue Type: Bug
> Environment: Windows
> MSVC compiler
> Reporter: Carel
> Assignee: Carel
> Priority: Major
>
> When building a C++ application using MSVC (2019) the following warnings are
> raised:
> [c4706|https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-4-c4706?view=msvc-160]
> {code}
> <...>\include\thrift\protocol\TBinaryProtocol.tcc(453) : warning C4706:
> assignment within conditional expression
> {code}
> This makes it impossible to build code using the warnings as errors option.
> One option could have been to mark the headers as external as discussed
> [here|https://learn.microsoft.com/en-us/cpp/build/reference/external-external-headers-diagnostics?view=msvc-160]
> but one should see on that page under Limitations:
> bq. Some warnings emitted by the compiler's back-end code generation aren't
> affected by the /external options. These warnings usually start with C47XX,
> though not all C47XX warnings are back-end warnings. You can still disable
> these warnings individually by using /wd47XX. Code analysis warnings are also
> unaffected, since they don't have warning levels.
> And as one would guess these all fall under that limitation.
> Disabling the warning globally does work, but is not ideal for hopefully
> obvious reasons.
