Well, internally getenv has to do lots of string compares to see if the 
variable is present in the environment, so no, getenv() vs. strcmp() is 
not a win.

However, if you check it once at the beginning of the load and then use 
a int/char * variable to remember if it was present, then yes it would 
be faster than the strcmp(), and we'd want to make it the first part of 
the expression for that very reason.
