I don't think we want to much too much effort into dbxout.c :-)
AIX assembler does not support continuation lines, but apparently one may be able to emit multiple, adjacent .stabx pseudo-ops if the string is broken at a grammatically correct location. In other words, "continuations" with a complicated string of characters to end one .stabx and start another. - David
