* gdb.stabs/alpha.mt: New configuration file for alpha.

* gdb.stabs/configure.in:  Use it.
	* gdb.stabs/ecoff.mt, weird-ecoff.sed:  Change sed script to enable
	sharing with alpha.mt, redefine long to word via preprocessor.
	* gdb.stabs/weird.def:  Conditionally adapt storage layout of v_comb
	for alpha.
	* gdb.stabs/weird.exp:  Handle compilation of weird.s by alpha
	native cc.
	* gdb.t00/teststrategy.exp:  Change expect string so that we
	consume the `(xgdb)' from the command echo and from the gdb prompt.
	* gdb.t05/expr.exp:  xfail "print unsigned int == (~0)" on the alpha.
	gdb currently compares all values as long, so this failure probably
	applies to any configuration where LONGEST is bigger than a target int.
	* gdb.t08/comp-info.c:  New file to determine if gdbme is compiled
	with gcc.
	* gdb.t08/Makefile.in, opaque.exp:  Use it. Alpha native cc is unable
	to handle opaque pointers, gcc is.
	* gdb.t21/gdbme.cc, gdb.t23/gdbme.cc:  operator new takes a size_t
	as first argument. Include <sys/types.h> and change all operator
	new definitions to use size_t.
	* gdb.t21/cplusfuncs.exp:  Handle changes in output for operator new
	now that we use size_t.
