>From the Free Pascal Programmer's Guide (section 1.1.41), there are 9
hard-coded compiler values that can be used in the format %xxx%. If it
is not any of those 9 hard-coded values, it is assumed to be an
environment variable, and will go fetch the value of that. If the
environment variable doesn't exist, an empty string is inserted.
