2nd draft: PRs fixed in 3.1.1

[Joe Buck <Joe dot Buck at synopsys dot com>]

This is the second draft.  Thanks to Peter Schmid and Volker Reichelt.
I was missing the libstdc++ and libjava PRs, and I rewrote some of
the descriptions.
--------------------------------------------------------------------------
This a set of PRs that are fixed in 3.1.1.  If anyone knows of
other PRs that will be fixed in 3.1.1, please let me know.  In
particular, if a PR wasn't mentioned in a ChangeLog somewhere,
you can assume I don't know about it.

My sorting is slightly different from the GNATS categories.

OPEN QUESTION: was PRs 6822 in the 3.1 release, or was it introduced later
in the 3.1 branch?  This is unclear from the report, and I haven't gotten
around to testing yet.

First, internal compiler errors (ICEs).  Some processor-specific ICEs
appear in the processor-specific section, the following PRs are present on
multiple platforms.

6255: (c++) ICE with implicit typename in a template
6643: ICE in assignment to var-size array
6706: (c++) ICE generating DWARF debug for var-length array
6723: (c++) ICE with template template parameter as default
6809: ICE in gcc 3.1 if -fverbose-asm is specified
6844: ICE when preprocessing file with lots of #defines
6892: (c++) ICE from #include inside switch() inside template function
7070: ICE with -Wunknown-pragmas and empty #pragma
7112: (c++) ICE on code involving templates and sizeof (name mangling issue)

C errors and optimization bugs

3467: c89 violation reported with -std=c99 -pedantic (var-size array)
6517: gcc hangs on C compile with multiple "-I-"
6660: typedef'd unnamed structs/unions don't compile with gcc 3.1
6677: bug in signed char treatment
6722: global register hoisted out of loop containing a call
6780: incorrect diagnosis of token pasting
6793: varargs function inlined inappropriately
7030: incorrect DWARF debug info emitted

C++ errors:
 189: DR 259: issue with explicit template instantiation
      There was an issue in the C++ language standard with respect to explicit
      and implicit instantiation of the same template (defect report #259).
      gcc 3.1.1 implements the resolution proposed to the ISO C++
      committee by Matt Austern, which will probably become official (see
      http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html#259 )

6381: Missing assembler label when -g is given (DWARF issue)
6611: Non-weak emission of std::__default_alloc_template, should be weak
6695: regression: template friend declaration doesn't work
6716: loop and fill ram during compiling
6747: C++ rejects inline assembly, C works
6944: default copy constructor doesn't work with multi-dimensional arrays
7145: g++ -O with struct initializer and return value opt generates bad code
7224: no diagnostic for unused ambiguous inline member functions
7279: gcc 3.1 named return value related miscompilation

libstdc++ errors:
3946: auto_ptr_ref constructor allows dangerous conversion
6282: bitset<0> results in nonsense behavior
6518: ostream << operator crashes when given a null pointer
6594: strstreambuf leaks 16 bytes - gcc 3.0.x
6648: interactive cin.getline(): need to type "return" twice

6795: stringbuf failure: segfault during >> after first underflow
6811: Missing 'return *this' in __enc_traits assignment operator in gcc 3.1
6886: bit vector iterator uses wrong 1 constant (affects 64-bit platforms)
7057: Operator== on hashtables doesn't appear to work correctly
7097: _GLIBCPP_HAVE_MBSTATE_T breaks non-GLIB systems
7173: _GLIBCPP_VERSION expands to an empty string in gcc 3.1

Objective-C:
6834: gcc 3.1 wrongly compiles some GNUstep code

libjava:
7292: java.lang.Character.toString(char) should be static

release (including 3.1.1):
