The issue is seen in the full output:
/vol/gcc/src/hg/master/local/libstdc++-v3/testsuite/28_regex/basic_regex/84110.cc: In function ‘void test01()’:
/vol/gcc/src/hg/master/local/libstdc++-v3/testsuite/28_regex/basic_regex/84110.cc:14: error: reference to ‘extended’ is ambiguous

/usr/include/floatingpoint.h:73: note: candidates are: ‘typedef unsigned int extended [3]’
Fixed by disambiguating extended. Tested on i386-pc-solaris2.11,
sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.
