Normally it is the programmer's responsibility to ensure that the ABI is 
met. In C++ standard Windows DLLs many compilers provide #pragmas for 
setting the ABI so that when one #includes the appropriate header file 
for a class or a function in a DLL, the correct ABI is specified. While 
a DLL/SO loading library might try to handle ABI in some way I just 
wanted to point out that compiler specific mechanisms often support it.
