>>From what I understand from MSDN, dllexport is supposed to substitute the export section in the .DEF file -

Your understanding is incorrect. What MSDN means is that you can export the function in one of two ways:

use the __dllspec( __dllexport ) tags
add an entry into the .DEF file

The compiler does not make any entries into the .DEF file for you -- you have to do that yourself if you want them there.

Prototyping the function as you did in a.cpp is not sufficient. You have to add dllexport in the function itself

a.cpp

__dllspec( __dllexport ) void a()
{
   // blabla
}

You can also export an entire c++ class

__dllspec( __dllexport) class MyClass
{
   // blabla
}
