2463 Sometimes on DOS and BeOS the temp output file cannot be opened.

2529 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus

2531 the table index in each of the asm output templates, instead ...

2570 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2571 invisible reference in registers, but then spilled to the stack.
2572 Remove code to emit a second stab for such parameters; it attempts
2573 to describe the value's location by introducing a synthetic C++
2574 `reference' type, and then saying the stack slot has that
2575 reference type. This loses type information (breaking GDB's
2576 `ptype' command, among other things) just to describe a location
2577 which stabs can represent correctly in other ways.
