Re: libstdcxx hangs

Hi.

FWIW, i have posted my Studio 12 compiler flags for SPARC V8/V9 and 
IA32/AMD64 here:

http://www.stefanteleman.org/libstdcxx/

With these compiler flags, and with the latest Studio 12 patches 
[http://developers.sun.com/sunstudio/downloads/patches/ss12_patches.jsp], 
i have successfully built all 4 shared versions of libstdcxx, which 
passes all the tests and runs all the examples.

Modulo a Studio 12 assertion when compiling collate.cpp on AMD64, 
which is fortunately not a showstopper since the nls localization 
files are generated successfully by the 32-bit build.
