Additions of functions is no problem; also modifying functions arguments/functionality is no problem. However, obsolete (i.e. unused) functions remain in the library (for old programs).
If the function interface is changed, the old function remains in the library (with the old version number) and the new version of the function is added. If symbol versioning is supported (e.g. under Linux), old programs continue to work flawlessly with new libraries. Thus: Library interface changes before 4.3.0 is released are nice, because one will not need to carry obsolete functions along; otherwise the development is not hampered at all. For procedure pointers, I expect that one doesn't need to touch the library at at all (but I might be wrong). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32580
