Not pretty but it can be done like this:
Enum1 = ENUMERATION {
[1]={1, "Forward"},
[2]={2, "Backword"},
[(not not BIDIERCTIONAL_SUPPORTED) and 3]={3, "BiDirectional"},
[4]={4, "None" }
}
which will leave an entry with a false key of BIDIERCTIONAL_SUPPORTED is
nil or false. Just ignore it. :-)
If you can change the syntax, then this is much better
Enum1 = ENUMERATION {
Forward=1,
Backword=2,
BiDirectional= BIDIERCTIONAL_SUPPORTED and 3 or nil
None=4,
}
