I do care about warnings and of course it's clear to me that things
won't work when there are undeclared functions. I just somehow got on
the wrong track here... I tried to reproduce what was crashing gftp and
isolated the code - that was when I noticed that the very same code
worked with c++ (ptsname declared), but not with c (ptsname not
declared). So I thought it might be a bug in gcc, but obviously I was
wrong with that.

Anyways, putting #define _GNU_SOURCE in two files fixed all the problems
and I mailed that tiny patch to the author.

So, thanks for your help and sorry for bugging you with this.
