[bug-gnulib] getline

[Simon Josefsson]

Hi.  I recall that the getline license was discussed before, but I
don't know if there ever was a conclusion.  So here goes.  I want to
use getline in GNU SASL, which is LGPL, but the implementation in
gnulib uses getndelim2, which is GPL.  There is a LGPL implementation
of getline/getdelim in glibc though.  Two ideas:

1) Don't call getndelim2 in getline/getdelim.  In other words, use the
   glibc implementation for getline/getdelim, and leave the getndelim2
   module as is in gnulib.

2) Relicense getndelim2.  Do we know who all authors are?  This would
   presumably be a first toward getting getndelim2 included in glibc.

#1 would lead to some code duplication, which is bad, but would also
mean we'd use the glibc code, which presumably is good.  #2 might be
difficult.

Thoughts?
