Hi John,
it's a matter of fact that getline() is a good thing and I fully
understand why you want to use it in the first place.

On the other hand I have to second Mojca and Apostolos.  TeX Live's
policy is to avoid forcing users to upgrade their systems in order to
run the latest release of TeX Live.  Users certainly don't understand
why they should do that while all other programs they use still work.

Hence, if autoconf is able to detect whether getline() is available or
not, I don't think it's worthwhile to remove the workaround in the
near future, regardless of its ugliness. 

Regards,
  Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
