Hi,

yes, in general this is a good idea. I just wonder how long these
constants have been in existence... i.e. if such a patch would
introduce compile errors on some relevant platforms. I guess the risk
is rather low for that because even with libftdi 0.20 this is a problem
and we want to migrate to libftdi 1.xx someday anyway.
Do you want to create a patch?
