 Revision history for Perl extension Time::HiRes.
 
+1.47
+       - do not use -lrt in Linux (from March Lehmann)
+               - unnecessary (nanosleep is in libc anyway)
+               - harmful (-lrt slows down execution)
+               - incompatible (with many distributions' pthreads)
+
 1.46
        - do not create files in blib directories under core
          (perl change #19160, from rgs)
