Thanks for that report, Janet confirmed it so I just reverted the commit that 
modified epicsSingleton.h a couple of weeks ago.

[I usually use 'make -s runtests' to silence the output from GNUmake and just 
display the test results BTW.]

Those numbers are right for src/libCom/test; if you do the 'make runtests' 
from the top level directory it also runs a second set of tests in src/db/test 
but they're not likely to fail.

Those failures are known bugs in some versions of Microsoft's optimizer, which 
assumes for example that the expression X-X will always give 0 (not true when 
X is NaN).

Interesting, we don't get that here; that's one of Jeff's tests, and it 
implies that socket() returned an invalid socket.  Did you have a working 
TCP/IP network connected to the machine at the time?

Thanks,
