It depends on whether you call it a bug or a feature. Most POSIX functions
only accept base-strings. READ-LINE may return an ordinary Unicode string,
which is not compatible with the POSIX calls.

Condition of type: SIMPLE-TYPE-ERROR
In function GETENV, the value of argument is
        "PATH"
which is not of expected type BASE-STRING

Nothing has changed in ECL, it is just that Unicode builds are now the
default and it triggered this unexpected condition. I just changed GETENV to
coerce its input to the appropriate type.
