c++ - extern const definition has internal linkage only

This is, I believe, a bug in the way that DMC++ treats the construct: extern const int whatever = 0; It will be compiled without being exposed for use by other translation units (in the beta compiler as of Aug 8). My understanding of C++ is that a const object can be given external linkage by prefixing its definition with the keyword 'const'. This can be seen in section "9.2 Linkage" of Stroustrup's "The C++ Programming Language" 3rd Ed. I'm pretty sure I've seen it in the standard as well, but I'm too lazy to dredge it up from my failed previous work machine. -- -Larry Brasfield (address munged, s/sn/h/ to reply)
