Experimental Physics and Industrial Control System

Hello, all!

I'm trying to build Diamond's nullhttpd module on Windows, but I'm
getting a "LNK2005: _free already defined in libcmt.lib(free.obj)"
error, among others.  Does anyone know what's the matter?

One result of my web search suggested that it means I'm mixing code
compiled with /MD with code compiled with /MT, but I'm not sure that's
the case.  I'm using defaults and compiling for the win32-x86 EPICS
architecture.

Here's the first error line (the full output of the build is at the end
of this email):

===
link -nologo -subsystem:windows -dll -LTCG -incremental:no -opt:ref -release -implib:nullhttpd.lib -out:nullhttpd.dll cgi.obj files.obj http.obj win32.obj config.obj format.obj server.obj main.obj MSVCRT.lib(MSVCR100.dll) : error LNK2005: _free already defined in libcmt.lib(free.obj)
===

Environment:

* 32-bit Windows 7 Pro
* Visual Studio C++ 2010 Express SP1
* 32-bit Strawberry Perl 5.26.2.1
* EPICS Base 3.14.12.7 + Known Problems patches
* EPICS_HOST_ARCH=win32-x86
* nullhttpd[1] 0-5-1dls5

Thank you!

Lewis
