Hi Mark,

I think there are some errors in your update of gxxint.texi. The N
code is not used for namespaces, they use Q instead. N is generated
for repeated types, such as

struct StructureName{};

void f(StructureName,StructureName,StructureName)
{}

which gives f__FG13StructureNameN20. Theoretically,
f__FG13StructureNameiN20 would be

void f(StructureName,int,StructureName,StructureName)
{}

but g++ genereates f__FG13StructureNameiT0T0 here. Under squangling,
the first one becomes f__FG13StructureNamen2 ('n' code, not demangled
yet), whereas the latter becomes f__FG13StructureNameiB0n1.

I'll check in the patch below.
