This is all true, but I think everyone is missing the point.  Wayne
Gong's original complaint was that since windbg can only read the MS
format of debug info (Codeview) it was unable to provide an accurate
location of a fault, a common observation when using a debugger without
debug info.  gcc cannot produce a format of debug information that
windbg can use -- whether it's embedded in the object or placed in a
separate file is totally irrelevant.
