I cannot tell much about implementation of namespaces in egcs-1.1.1 as I haven't
used them. At least information in egcs homepage says that namespaces are
supported. But I don't think that egcs-1.1.1 is so "embryonic".
Main reason why I suggested DJ to put DJGPP port of egcs-1.1.1 in directory
v2gnu/beta instead of simply v2gnu was problems with C++ exceptions handling.
Currently the source of these problems is found and perhaps next version
of binary archives will perhaps no more have this problem.
There are problems with using STL (linker errors) but I don't thing gcc-2.8.1 is
better here. As I know there is also similar problems even under Linux.
Also collect2 from DJGPP "official" binaries of egcs-1.1.1 fails to recompile source
if that is needed and command line options -frepo is being used. But as I said
I think that gcc-2.8.1 is not better.
So I think it could be Ok to try egcs-1.1.1. However if exceptions support is really
needed there is 2 possible ways how to fix it:
- applying rather small patch to egcs-1.1.1 sources for DJGPP and rebuilding;
- using development snapshots of binutils;
