Hi Michael,

Visual Studio C runtime used 3 digit exponents by default prior to VS 2015, but you can change this behaviour.
 
https://msdn.microsoft.com/en-us/library/0fatw238(v=vs.120).aspx

in VS 2015 the above function is withdrawn and 2 digit exponents are used, so you'd need to protect any usage of this function with something like

#if defined(_WIN32)  && defined(_MSC_VER) && (_MSC_VER < 1900)

Regards,

Freddie

the dllimport/export issue is fixed.  My mistake in including epicsExport.h in the wrong place.

The test failure is at least diagnosed:

> not ok 739 - cvtFloatToString(1e+08, 6) == 12 (13) -> "1.000000e+008"
>     ok 739 - cvtFloatToString(1e+08, 6) == 12 (12) -> "1.000000e+08"

An extra zero in the exponent.  I don't see this as a blocker for a pre-release.

I also fixed an issue with the filterTestHarness and filter registration.  The RTEMS tests, individual and test harnesses, now pass for me with qemu.
