Link Time Optimization

[David]

I've been searching mailing list for supporting -flto in libtool, and seen 
several (commited?) patches.

The problem is that I've tried git version of libtool (trunk) and still it is 
not supported since any program will compile with -flto (for example, 
mysql-5.1.50).

Then, I have several questions:
- Are the lto patches already commited to trunk, or are they in some other 
branch?

- When will be (officially, or alpha) supported lto in libtool, in which 
version 
is planned to?

Thanks, and sorry if I am missing something, but I couldn't find this info on 
google :)
