1034 Sometimes on DOS and BeOS the temp output file cannot be opened.

1100 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
1101 MEM for program memory word reference. Do not add the label to
1102 the table index in each of the asm output templates, instead ...

1141 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1142 invisible reference in registers, but then spilled to the stack.
1143 Remove code to emit a second stab for such parameters; it attempts
1144 to describe the value's location by introducing a synthetic C++
1145 `reference' type, and then saying the stack slot has that
1146 reference type. This loses type information (breaking GDB's
1147 `ptype' command, among other things) just to describe a location
1148 which stabs can represent correctly in other ways.
