[Bug c/18523] New: Documentation should discuss removal of generalized lvalues

[austern at apple dot com]

gcc 4.0 has a new feature: it no longer recognizes generalized lvalues.  The documentation doesn't say 
anything about it, however.  Instead, the section on generalized lvalues from 3.4 has just been 
removed.

This isn't reasonable.  Users who are familiar with previous versions of GCC shouldn't have to do an 
exhaustive search through the documentation to find that something isn't there, and then interpret the 
absence from the documentation correctly, in order to learn of such a major change.  The 
documentation should clearly say that generalized lvalues have been removed, and should give users 
advice on how to fix older code that relied on this extension.
