[Bug c++/34166] -fleading-underscore duplicate underscore in some template cases

[shockenhull at niceberg dot com]

------- Comment #3 from shockenhull at niceberg dot com  2007-11-28 22:23 -------
the problem is in the pre-compiled c++ library

work around:

using option -D_GLIBCXX_EXTERN_TEMPLATE=0 
disable pre-compiled templates in the c++ headers and force correct
instanciation when -fleading-underscore is used

thanks to Andrew Pinski for pointing to the "extern template" feature.

maybe overriding the platform's defaut underscore prefix should define
_GLIBCXX_EXTERN_TEMPLATE=0 if not overriden explicitly so the glitch wont come
up?
