Hi Mark,

I found a problem compiling 3.14.12.5 (with the msvs-timespec.patch) when building with the latest version of MinGW on Windows, which is gcc 5.3.0.

 

This is the error:

I was able to fix the problem by using the version of osdTime.h from base-3.15.4.

That looks like a request to apply the patch from
    http://bazaar.launchpad.net/~epics-core/epics-base/3.15/revision/12717
to the 3.14 branch, is that right?

Cheers,
~Ralph

ps. Wouldn't that rather be a core-talk subject?
