The nanosleep() at valgrind-listener.c:120 is just a poor emulation
used under Windows, because this function is not available in MinGW by
default.

For example, my pthread_time.h contains just this:
/* Dummy header, which gets overriden, if winpthread library gets installed.  */
So that's why it have been working for people so far.

You (or something on your behalf) have apparently installed the
winpthread package and it contains something more, including a
prototype for a proper nanosleep(), provided by the library. That's
the conflict.

This probably needs some proper handling in the configure script and
an #ifdef. In the meantime, you can e.g. just delete the nanosleep()
emulation from valgrind-listener.c, it will use the system one.
(Though you might need to add -lpthread to valgrind_listener_LDADD in
auxprogs/Makefile.am to satisfy the new dependency then.)

Kind regards,
Jiri
