 i suspect some weird bad build issue.  i don't see this on my
 4 weeks ago mips64eb build:

 transitions ~> echo _ZNSt15basic_streambufIcSt11char_traitsIcEE7seekoffElS=
 t12_Ios_SeekdirSt13_Ios_Openmode | c++filt
 std::basic_streambuf<char, std::char_traits<char> >::seekoff(long, std::_I=
 os_Seekdir, std::_Ios_Openmode)
 transitions ~> l /usr/bin/c++filt
 -r-xr-xr-x  1 root  wheel  198832 Jan 28 01:13 /usr/bin/c++filt*

 ie, the demangler seems busted..

 i'll update my er4 and see what happens.
