Er... Maybe I was both imprecise and rude, but english is not my first
language.

ftxpost.c is in freetype1-1.5.20020624/lib/extend.

Remark that if the names are given in a striclty increasing order, both
algorithms give a correct result.

Here is the piece of code which does the name indexing part in pdftex,
and which looks (to me) as respecting the specification (but I may be
wrong):
        for (glyph = glyph_tab; glyph - glyph_tab < nnames; glyph++) {
            if (glyph->name_index < NMACGLYPHS) {
                glyph->name = mac_glyph_names[glyph->name_index];
                tex_printf("\nAdding glyph %.4X named '%s' in place
%u",glyph->name_index,glyph->name,(unsigned int)(glyph - glyph_tab));
            }
            else {
                p = glyph_name_buf;
                k = glyph->name_index - NMACGLYPHS;
                for (; k > 0; k--)
                    p = strend(p) + 1;
                glyph->name = p;
                tex_printf("\nAdding glyph %.4X named '%s' in place
%u",glyph->name_index,glyph->name,(unsigned int)(glyph - glyph_tab));
            }
        }

Note the k loop that searches the k-th name instead of taking the first
available.
