IMHO stack of warnings should be made singleton object (as in design
pattern).

You could implement it in C using static stack somewhere in warning.c, and
accessor functions, available in warning.h:

init_warnings();

add_warning(msg);

list = get_warnings();

This does not require of you to change interface of any function, and will
be implemented in no more than 100 lines, including extensive copyright
info :)
