Confirmed. In fact, I get ICEs with newer versions of gcc with your code: 
 
g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc 
x.cc:12: redefinition of `m' 
x.cc:2: `m' previously declared here 
 
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc 
x.cc:12: error: redefinition of `m' 
x.cc:2: error: `m' previously declared here 
x.cc:12: internal compiler error: tree check: expected var_decl, have  
   namespace_decl in warn_extern_redeclared_static, at cp/decl.c:3278 
Please submit a full bug report, 
with preprocessed source if appropriate.

x.cc:12: internal compiler error: tree check: expected var_decl, have

The ICEs are a regression, as is the fact that we now don't even get to see 
the original error message any more.
