Hi exports,  
When I update USD toolkit to 24.03 from 22.08, the compiler reports three new warnings:  
C4003: [Compiler Warning (level 1) C4003](https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-1-c4003?view=msvc-170)

Is there anyone met the same issue? Should we ignore these warnings?

I can comment on C4003. Here is a related issue.  
[Warning C4003 · Issue #2624 · PixarAnimationStudios/OpenUSD (github.com)](https://github.com/PixarAnimationStudios/OpenUSD/issues/2624)

As OpenUSD has become less dependent on boost and the preprocessor, less things now include `pxr/base/tf/preprocessorUtils.h` which had the warning suppressing `ARCH_PRAGMA_MACRO_TOO_FEW_ARGUMENTS` macro. I thought there was a fix made to disable that warning in the OpenUSD `CMake` files so I’m surprised you’re seeing it.

BTW: I just wanted to say **Thank You** for continuing the work on removing `boost` where possible. It’s much appreciated. 👍🏻
