Getting warmer ;-)

Similarly to drop_privileges() you can create prepare_credential that takes "struct cred *, const char *username, const char *groupname" as another helper, and make its implementation on the NO_POSIX side barf/die when called, saying that switching credentials is not supported in NO_POSIX implementation. That way, you can keep the main clean without any conditionals. Command line argument parser can (and probably should) stay the same between implementations.

Thanks.
