Searching for the presence of "Visual Studio 10.0" in the PATH environment variable might work.  I don't know if the problem exists in versions of Visual Studio earlier than 2010.  Are those supported by EPICS base 3.15.4 anyway?

I believe it is only necessary for SHARED_LIBRARIES=NO.  That was definitely true before I removed the optimization disabling from src/LibCom/calc/calcPerform.c.  I need to test that dynamic builds still work after that change, but I suspect they will.  I will test that today.

Interesting. I was actually thinking more along the lines of checking 
for the presence of environment variables like %VS120COMNTOOLS% (for VS 
12.0 = 2013) or %VS100COMNTOOLS% (for VS 10.0 = 2010).
Your idea would also get the architecture, but make should know that 
already.
Is your fix necessary for SHARED_LIBRARIES=NO or STATIC_BUILD=YES? Or 
both, or any?
