Andrew Koenig did provide an unofficial list of the changes between the
98 standard and the 2003 technical corrigendum, see:

Oh yes, the changes between C++03 and C++11 are much greater!

Compared to the changes between C++03 and the new C++11 standard I would
agree with your colleague, see also Bjarne Stroustrup's summary:
http://www2.research.att.com/~bs/bs_faq.html#C++03

Nonetheless there were a number of relevant fixes made in the core
language, which are "observable" between corresponding compilers. IMO a
god survey provides the status list here:
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_status.html

Just search for the text "Issues with "TC1" Status:" and look at the
following table. Another view on the same issues of the core language
can be found here:
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#TC1%20Status

If you are interested in the changes for the library as well, see at:
http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-status.html

(Search for "TC1 (125 issues)")

Are you sure that you talk about proposals for C++03? It is true that a
lot of proposals were made around 2003+, but these drastic changes were
not considered for C++03. I do not know whether at some point of point
the decision on this was not clear, but C++03 is more or less a
"bug-fixing release". The official name for it was "Technical
corrigendum" ISO/IEC 14882:2003.

Up to C++11 no international standard was released, but the language was
improved in smaller issue steps. These steps are usually called CD1 and
CD2 (CD stands for "Committee Draft") and for the library the so-called
TR1. A good survey can be found here:
http://en.wikipedia.org/wiki/C%2B%2B

and here:
