take it with a grain of salt.

I would remind Joerg that the Austin group is considering standardizing
the GNU getline() interface; and if that is ever standardized, the
older interface will be officially obsoleted. Meanwhile, getline() is
a non-standard interface; and until either version (the 1982, or
the GNU version) is standardized, cygwin is sticking with the
Linux definition, and that programs that want to be portable
to multiple platforms must be prepared to deal with whatever
definition of getline exists.

The only thing cygwin could do here is to make sure that
the definition of getline is not visible if _POSIX_SOURCE is
defined, since it is an extension to POSIX. From what I
know about Joerg, he is pretty insistent that his programs
stick to standards, so if he uses _POSIX_SOURCE to protect
himself from inheriting getline from system headers, then it
is cygwin's fault that we do not yet isolate non-standard
