While upgrading sqlite3 to version 3.52 for MXE, I encountered this link failure:

I suspect the preprocessor logic in shell.c regarding wmain, defined under _WIN32, including MINGW. In version 3.51.2, wmain was not defined under MINGW. The following patch fixes the problem for me:

diff --git a/shell.c b/shell.c

Thanks. sqlite-20260307120056-d95b9e7c17 builds perfectly.
