Right now, gcc provides --std=c++0x to turn on all the features from C++0x that
it's implemented. However, it would be useful for organizations migrating to
C++0x to turn on one feature at a time as that feature becomes stable. For
example, we might turn on -fenable-c++0x-auto before -fenable-c++0x-lambdas.

We are too slow already. * We have too many open PRs, so it is not worth it to keep this open just in case. Sorry about this but I hope you can understand. -- manu at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |manu at gcc dot gnu dot org Status|UNCONFIRMED |RESOLVED Resolution| |WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44244 ^ permalink raw reply [flat|nested] 4+ messages in thread
