Looks like the correct structure.

I also (on Debian GNU/Linux) have a /usr/include/sys/time.h but that
is different from /usr/include/time.h. Can you check in ctime (should
be in /usr/include/c++/<version>/ or something similar) which time.h
is included and if timespec is defined in that time.h?

I've seen this before. It's a problem with a faulty printw() in the
curses lib on your system. It should accept a const char* and should
not need a char*. You can get around this by disabling curses:

    ./configure --disable-curses
