1. This issue has already been thoroughly discussed and beaten to death
in the list archives over and over again.  Saying "please look into it"
sounds like you haven't actually done any of this looking yourself.

2. In current versions of Cygwin getline and getdelim are only defined
if the user defines _GNU_SOURCE - this is the same way it's done on
linux.

        * include/features.h: Add comment to explain what's going to
happen
        here at one point.
        * include/sys/stdio.h: Guard getline and getdelim prototypes
with
        _GNU_SOURCE to avoid collision with old-style declarations.

3. If your code blindly uses "getline" without checking for an existing
version then it's probably broken -- as mentioned in these previous
threads, the Austin group will likely be adding the GNU version of
getline to the next revision of the POSIX standard, meaning your source
will soon be officially noncompliant.
