sparc-sun-solaris2.7 bootstrap fails RTL checking

[Kaveh R. Ghazi]

When I use --enable-checking=misc,tree,rtl,gc (i.e. add "rtl" to the
other checks on by default) on sparc-sun-solaris2.7 I get the
following error after the 3-stage bootstrap compiling
libstdc++/sinst.cc:

I first reported this a few weeks ago in:
