this patch broke Solaris bootstrap with /bin/as:
/vol/gcc/src/hg/trunk/local/gcc/dwarf2out.c: In function 'void
output_rnglists()':
/vol/gcc/src/hg/trunk/local/gcc/dwarf2out.c:11055:8: error: unused variable
'basebuf' [-Werror=unused-variable]
char basebuf[MAX_ARTIFICIAL_LABEL_BYTES];
^~~~~~~
/vol/gcc/src/hg/trunk/local/gcc/dwarf2out.c:11088:16: error: unused variable
'len' [-Werror=unused-variable]
unsigned int len = vec_safe_length (ranges_table);
^~~
Fixed as follows; will commit as obvious once i386-pc-solaris2.12 and
sparc-sun-solaris2.12 bootstrap have finished successfully.
