I've filed [Haiku issue 18258](https://dev.haiku-os.org/ticket/18258) on Clang not defaulting to generating PIC. Clang not behaving like GCC renders it painful to use with software that uses autotools or CMake.

> Let's give Clang some time then. "Give Clang some time" as in "time to get issue 18258 fixed", presumably. In 21f46b9600c4886b83dd2dbc4db1efb2bfdc722d I added a check, on Haiku, for whether...

[Haiku issue 18258](https://dev.haiku-os.org/ticket/18258) now appears to be fixed with llvm12_clang-12.0.1-5, so I removed the -fPIC hacks. The entire build matrix ran, at least on my VM, after updating the compiler...

> 8007007e (ERROR_MOD_NOT_FOUND) Presumably that's a result of mapping the Windows error code `ERROR_MOD_NOT_FOUND` to an `HRESULT` as per [Microsoft's documentation on that mapping](https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/0c0bcf55-277e-4120-b5dc-f6115fc8dc38).

Note also that a lot of the packet capture code on any platform is in the underlying capture mechanism that libpcap uses. On Windows with Npcap, that's the Npcap NPF...
