I suspect the real question was more about RTTI and/or exception
handling, both of which complicate C++ enormously (compared to C).
Of course, comp.lang.c is the wrong newsgroup on which to discuss
either one.

Indeed.

(In theory, of course, a C++ program that avoids using the RTTI
and exception features -- and much of the rest of C++ along with
them, since, e.g., "new" now throws exceptions -- could compile to
similary-small static-linked binaries. Of course, if one is going
to avoid all these C++ features, I would wonder why that one is
writing C++ code at all. If one simply wants, e.g., the convenience
of variable declaration at point of first use, C99 supports that
already; and quite a few C compilers, while not yet "full C99",
include this now as well.)

Last, a note to the original poster: the phrase "clear doubts", in
English, as used in the subject line means approximately: "these
are things I am pretty sure are wrong", not "could you expound on
something so as to clear up some questions I have". The word
"clear" here takes the role of an adjective, modifying the noun
"doubts", and means "these doubts are clear (i.e., should be obvious
to all)". The word "doubt", in turn, does not translate directly
to "question", but rather to "questionable items" or "dubious
things". The phrase "clear up", in which clear is a verb (rather
than an adjective), *does* mean "answer questions", but the word
"up" is usually required.

English, she is a funny old language. :-)
