>Description:
Currently, it is only possible to turn off the 
implicit typename extension through -pedantic. Since the
compiler then operates too restrictive for many applications,
turning this extension off alone is desirable, e.g. through
a -fimplicit-typename flag.

It is also desirable that the extension becomes documented; 
it is currently mentioned only in c-tree.texi.
