Errors or warnings in templated functions often print a ridiculously long type 
name, especially when the STL is involved, as in 
 
/home/eschnett/Calpha/Cactus/configs/einstein-gfortran-debug/build/CarpetRegrid/centre.cc: 
In function `int CarpetRegrid::Centre(constcGH*, constgh<3>&, int, int, int,

__gnu_norm::vector<__gnu_norm::vector<int, std::allocator<int> >, 
std::allocator<__gnu_norm::vector<int, std::allocator<int> > > >&)': 
/home/eschnett/Calpha/Cactus/configs/einstein-gfortran-debug/build/CarpetRegrid/centre.cc:46: 
warning: comparison between signed and unsigned integer expressions 
 
 
 
I never typed in all this "allocator" and "__gnu_norm" stuff.  I assume these 
are default template parameters.  Would it be possible to not print them?  It 
would make the warning message readable. 
 
Oh.  I just see that there is no space after the "const" keywords.  Is that 
intentional?
