Inline namespace definitions are a feature proposed under C++0x. The feature
is not part of the C++98/03 standards. Code that uses it under -std=c++98
-Wall -Wextra -pedantic should get at least a warning.
berg...@etna:~/gcc/BUGS/> cat t.cpp
inline namespace A { }
berg...@etna:~/gcc/BUGS/> g++ -std=c++98 -Wall -Wextra -pedantic -c t.cpp
berg...@etna:~/gcc/BUGS/> echo $?
0
This seems to also be the case for GCC 4.4 and 4.5.
