Let's consider the function: 'void foo(struct S*);' If two ELF binaries contain a definition of that function foo which ELF symbol is exported, if the type struct S hasn't changed, and if the only difference between the ELF binaries is that foo was defined in the translation unit a.c in the first binary and in b.c in the second binary, then the comparison engine of libabigail (which is the library that abidiff uses) will consider the declarations of the two foo functions as being equal -- no matter what include file comes before the definition point of foo in a.c and b.c. If it does not, then it's a bug that ought to be fixed. If you feel that I haven't understood your question, then I guess a minimal standalone example (in the form of C source code) that illustrates your use case could be helpful to me.
