I'm branching off from the current discussion about the minimum 
supported C++ language version for Boost. If Boost goes C++14 and my 
customer is still on C++03, I'm concerned about my DLL being compatible 
with their EXE. (I don't expose Boost or STL in my headers. Nor do I 
expose C++ strings. Allocations don't cross the EXE/DLL boundary, using 
factory constructors and destroy methods.)

But I do worry about the ABI compatibility. According to MS, linking is 
allowed between compiler versions if the latest linker is used, but they 
don't say anything about language versions.
