I haven't tested it on that platform, though I expect it to work since 
it relies only on current_timespec and Emacs already uses that.

I just now added some test cases to Gnulib for it; see the patch in the 
first attachment. You can try these tests in your environment by running 
'./gnulib-tool --test gettime-res' in the Gnulib source directory. Or 
you can save time by running './configure; make check' in the directory 
represented by the second attachment, which is a compressed tarball 
containing the output of './gnulib-tool --create-testdir --dir 
test-gettime-res gettime-res'.
