Bootstrap failure on sparc-sun-solaris2.10

[Art Haas <ahaas at impactweather dot com>]

Hi.

This morning's build on sparc-sun-solaris2.10 failed for me; the error
message in 'stage_2' is below:

options.c:753:3: error: enum conversion in initialization is invalid in C++ [-Werror=c++-compat]
options.c:753:3: error: (near initialization for 'global_options_init.x_sparc_cpu_and_features') [-Werror=c++-compat]
options.c:755:3: error: enum conversion in initialization is invalid in C++ [-Werror=c++-compat]
options.c:755:3: error: (near initialization for 'global_options_init.x_sparc_cpu') [-Werror=c++-compat]
cc1: all warnings being treated as errors

My build on Friday worked, so the likely culprit is this change
from today:

2011-03-28  Joseph Myers  <joseph@codesourcery.com>

	* config/sparc/sparc-opts.h: New.
	* config/sparc/sparc.c (sparc_handle_option, sparc_select,
	sparc_cpu, fpu_option_set, TARGET_HANDLE_OPTION): Remove.
	(sparc_option_override): Store processor_type enumeration rather
	than string in cpu_default.  Remove name and enumeration from
	cpu_table.  Directly default -mcpu then default -mtune from -mcpu
	without using sparc_select.  Use target_flags_explicit instead of
	fpu_option_set.
	* config/sparc/sparc.h (enum processor_type): Move to
	sparc-opts.h.
	(sparc_cpu, struct sparc_cpu_select, sparc_select): Remove.
	* config/sparc/sparc.opt (config/sparc/sparc-opts.h): New
	HeaderInclude entry.
	(mcpu=, mtune=): Use Var and Enum.
	(sparc_processor_type): New Enum and EnumValue entries.

The relevant lines of the auto-generated 'options.c' file look like this:

752:  0, /* sparc_cmodel_string */
753:  0, /* sparc_cpu_and_features */
754:  0, /* sparc_std_struct_return */
755:  0, /* sparc_cpu */
756:  0, /* asm_file_name */

Thanks, as always, to everyone working on GCC.
