Actualyl the way the JNI works it doesn't permit to load *ANY* DLL that
depends on another DLL, that leads to a crash.

BTW: does Windows even have a gettimeofday()?

If it has it, it is 10ms-bound for sure, anyway.
I would rather use some native method to call RDTSC, then work on the
Java side to interpolate "more precise" time.
Or use it directly, if you only need a monotone counter, regardless of
real time.

Take a look here:
<http://home.lapo.it/cgi-bin/viewcvs.cgi/lapint/it/lapo/util/>
specifically files Makefile, RDTSC.c and RDTSC.java
