How do you compile for Windows?

[gitartdev]

I've successfully compiled pgaudit for windows but I can't get set_user to compile against PostgreSQL 16. I've tried multiple versions. Version 4.1.0 returns the error:

C:\dev\set_user_cl>cl /c @.\compile_response_file.txt .\set_user.c set_user.c C:\Program Files\PostgreSQL\16\include\server\pg_config_manual.h(141): warning C4005: 'EXEC_BACKEND': macro redefinition C:\dev\set_user_cl\set_user.c: note: see previous definition of 'EXEC_BACKEND' C:\dev\set_user_cl\set_user.c(190): error C2375: 'set_user': redefinition; different linkage C:\dev\set_user_cl\set_user.c(101): note: see declaration of 'set_user'
