Hello fellows,
I have my bird config failing on something as trivial as
if defined (some_variable_never_defined)
then ... ;
with "syntax error, unexpected CF_SYM_UNDEFINED" on the "some_...".
Am I wrongly assuming that defined() would check for the variable to exist
within BIRD's global scope (e.g., appear in the namespace)?
How, if not this way, can I check for a variable to have been defined prior
(and, if it does, do certain things, of course)?
Elmar.
PS: The first example on the filters page makes me believe that defined() works
in exactly this way, but I might be mistaken.
