 > The original six lines try to check whether the invocation of
 unsetenv(KRB5_ENV_CCNAME) returns an error, and if so that the error
 happened while clearing the environment variable KRB5_ENV_CCNAME. Since on
 Tiger unsetenv() is a void function, i.e. it does not return a return
 value, it's not possible to check success this simple way. A real
 substitute of the original six lines would try to read the environment
 after clearing and report then that clearing failed.

 It is what I've done with my patch : unsetenv() then check with getenv()
