[Boost-users] GCC and precompiling headers containing anonymous namspaces (i.e. bind/placeholders.hpp)

Like a number of other compilers, GCC (version 3.4.3) appears to have 
problems related to precompiled headers that contain anonymous 
namespaces - such as the one in bind/placeholders.hpp.  There appears to 
be some consensus that GCC currently does have issues in this area (see 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10591).

I noticed the workarounds in bind/placeholders.hpp (Boost version 
1.32.0) for other compilers, and tried them with the above version of 
GCC.  I discovered that only the work-around using static inline wrapper 
functions (i.e. the one for Borland compilers) seems to work.

Can anyone confirm this?  Should I file a bug to have that workaround 
apply for GCC, as well?  Are anonymous/unnamed namespaces used in any 
other BOOST headers (which should presumably also have the workaround)?
