Win go get fails with clang

[ghost]

I try to install this package using the clang compiler:

PS > $env:CC = "C:\PROGRA~2\MICROS~1\2019\COMMUN~1\VC\Tools\Llvm\bin\clang.exe"
PS > $env:CXX = $env:CC
PS >  go get -v github.com/mattn/go-sqlite3
github.com/mattn/go-sqlite3
# github.com/mattn/go-sqlite3
LINK : fatal error LNK1104: Datei "mingwex.lib" kann nicht ge�ffnet werden.
clang: error: linker command failed with exit code 1104 (use -v to see invocation)

The build fails because the binary is linked against the library mingwex (don't know what it is):

However, I cannot use the library in another project, because the linker errors out. I suspect that the clang target is incompatible with the go linker, but I'm not sure.
