The gltests/config.log file contains:
configure:30414: checking whether tcgetsid is declared
configure:30414: result: yes
however ./config.log contains the content below. What's interesting is
that there is no #include <termios.h> which I believe is needed? I'm
not sure why the check in gltests/ works, but maybe other headers are
enabled there, and the tcgetsid prototype gets defined indirectly.
