I assume you are using today's CVS?

can you go to 

/usr/local/src/tmp/gcc-2.96/i686-pc-linux-gnu/libstdc++-v3/src
(or wherever your libstdc++-v3 "src" build directory is)

and type 

make locale.o

?

And paste in the error message you get? I suspect you'll see Internal 
Compiler Error....

I got a bootstrap on 

gcc.20000910/

However I am finding it difficult to debug with compilers of this vintage 
or later, as locale.cc is mis-compiled somehow and dwarf2 debug info goes 
wacky, prohibiting the use of gdb. I talked to jason about this, and he 
knows the details, so at some point in the future we'll see this fixed.

In the meantime, I suggest using this vintage:

gcc.20000827/
