make check just finished and looks reasonably well:

So this platform seems to need -fcheck-references as well. Unfortunately
my proposed patch (included below for reference) to enable this on
platforms that need it revealed a problem:
* bootstrap on sparc-sun-solaris2.8 failed compiling
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/java/lang/Boolean.java: In class `java.lang.Boolean':
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/java/lang/Boolean.java: In constructor `(boolean)':
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/java/lang/Boolean.java:90: can't reassign a value to the final variable 'value'.
 	this.value = value;
 ^
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/java/lang/Boolean.java:79: final field 'value' may not have been initialized
1 error
 This error vanishes if compiling with -fno-check-references.
* bootstrap on i686-pc-solaris2.8 succeeded, but apart from fixing some
 testsuite failures as expected, it introduced a couple of new ones:
+FAIL: final_initialization_in_ctor compilation from source
+FAIL: final_initialization_in_ctor -O compilation from source
+FAIL: final_static_and_friend compilation from source
+FAIL: final_static_and_friend -O compilation from source
+FAIL: final_int compilation from source
+FAIL: final_int -O compilation from source
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/testsuite/libjava.compile/final_initialization_in_ctor.java: In class `final_initialization_in_ctor':
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/testsuite/libjava.compile/final_initialization_in_ctor.java: In constructor `(int,float)':
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/testsuite/libjava.compile/final_initialization_in_ctor.java:19: can't reassign a value to the final variable 'loadFactor'.
 this.loadFactor = loadFactor;
 ^
/vol/gnu/src/gcc/gcc-3.1-branch-dist/libjava/testsuite/libjava.compile/final_initialization_in_ctor.java:10: final field 'loadFactor' may not have been initialized
1 error
Any suggestions what to do about this?

	* configure.host: Introduce host_cpu and host_os switches, moving
	cpu- or os-only sections here.
	Sort host switch.
	* configure.host (REFERENCESPEC): New.
	* libgcj.spec.in (jc1): Use it.

	* configure.host (solaris2*, mips-sgi-irix6*): Use
	-fcheck-references for REFERENCESPEC.
	
	* configure.host (i?86-*-solaris2*): Keep default DIVIDESPEC.
