    compile: Use -Wall, not -w
    
    For a reason unknown to me GDB was using -w instead of -Wall for 'compile code'.
    The problem is later patch for 'compile printf' really needs some warnings to
    be able to catch for example missing format string parameters:
    	(gdb) compile printf "%d\n"
    GCC does not seem to be able to cancel -w (there is nothing like -no-w).
    
    Besides that I think even 'compile code' can benefit from -Wall.
    
    That #ifndef change in print_one_macro() is needed otherwise we get
    macro-redefinition warnings for the GCC built-in macros (as -w is no
    longer in effect).  For example, without the #ifndef/#endif one gets:
    
    	compile -r -- void _gdb_expr(){int i = 5;}^M
    	/tmp/gdbobj-xpU1yB/out4.c:4:0: warning: "__FILE__" redefined [-Wbuiltin-macro-redefined]^M
    	/tmp/gdbobj-xpU1yB/out4.c:5:0: warning: "__LINE__" redefined^M
    	...
    
    It makes more sense to pick the inferior's version of the macros, hence
    #ifndef instead of #undef.
    
    That new testsuite XFAIL is there as if one changes the struct definition to be
    compliant with cv-qualifiers (to prevent the warnings):
    struct struct_type {
    -  struct struct_type *selffield;
    +  volatile struct struct_type *selffield;
    only then GCC/GDB will hit the crash, described in that GDB PR 18202.

    2015-05-16  Jan Kratochvil  <jan.kratochvil@redhat.com>
    
    	* compile/compile-c-support.c (print_one_macro): Use #ifndef.
    	(generate_register_struct): Use __gdb_uintptr for TYPE_CODE_PTR.
    	(c_compute_program): Call generate_register_struct after typedefs.
    	* compile/compile-loc2c.c (push, pushf_register_address)
    	(pushf_register): Cast to GCC_UINTPTR.
    	(do_compile_dwarf_expr_to_c): Use unused attribute.  Add space after
    	type.  Use GCC_UINTPTR instead of void *.  Remove excessive cast.
    	(compile_dwarf_expr_to_c): Use GCC_UINTPTR instead of void *.
    	* compile/compile.c (_initialize_compile): Enable warnings for
    	COMPILE_ARGS.
    
    gdb/testsuite/ChangeLog
    2015-05-16  Jan Kratochvil  <jan.kratochvil@redhat.com>
    
    	* gdb.compile/compile-ops.exp: Cast param to void.
    	* gdb.compile/compile.exp: Complete type for _gdb_expr.
    	(compile code struct_object.selffield = &struct_object): Add xfail.

This has been primarily fixed in GCC.

But some commit was done also for GDB-7.10:
