A single-file branch to help me keep things straight while adapting
GDB to the GNU V3 C++ ABI.

* c-typeprint.c: Commit Dan Berlin's changes.

* config/sparc/tm-sp64.h (GDB_MULTI_ARCH): Down grade to
GDB_MULTI_ARCH_PARTIAL from two.  SOFTWARE_SINGLE_STEP is not
multi-arch.
* gdbarch.sh (SOFTWARE_SINGLE_STEP): Add.
* gdbarch.h, gdbarch.c: Re-generate.
* target.h (SOFTWARE_SINGLE_STEP_P)
(SOFTWARE_SINGLE_STEP): Delete macro definitions.

Re-vamp the register code so that a lot more is routed through
{read,write}_register_gen.  Hook that function with multi-arch.

Remove extraneous whitespace

Fix compile time warnings.

* stabsread.c (read_cpp_abbrev): Properly construct the names of
virtual function table pointer fields.

merge from gcc

* defs.h (xfree, mcalloc, mmalloc, mrealloc, mfree, xmmalloc,
xmrealloc): Move existing declarations to the one place and
re-order to be consistent.
(xmcalloc, xmfree): Declare.
(xmmalloc, xmrealoc): Assume ISO-C - use size_t and void* in
declaration.

* utils.c (size_t): Delete #ifdef defining size_t.
(mmalloc, mrealloc, mcalloc, mfree): Re-order.
(mmalloc, mrealloc, mcalloc): Document as only calls in GDB
corresponding malloc, realloc, calloc.
(mfree): Call free directly.
(xmmalloc, xmrealloc): Clean up. Assume ISO-C.
(xmcalloc, xmfree): New functions. Copy old xcalloc and xfree
function bodies to here.
(xcalloc, xfree): Call xmcalloc and xmfree respectfully.

Fix -Werror -Wuninitialized warnings.

Add note about inability to use "make distclean" in maintainer mode.
