>Description:
If a class member of an anonymous struct type has the same
name as some namespace declared earlier, the compiler reports
a "parse error". If the struct definition is separated from
the member declaration, however, everything goes well. 
>How-To-Repeat:
Compile the attached code without and with -DWORKAROUND.
>Fix:
A workaround is illustrated in the attached sample code.

Personally I don't like this style; however, there is a lot
of code written in this manner (in my case it was GTK)
which one might want to weave together with own things.
