[4.3][doc patch] document new tree-codes for multipletypes vectorization project, and fortran build problem

[Dorit Nuzman <DORIT at il dot ibm dot com>]

While preparing the multiple-datatypes project to be committed I realized I
never got this bit reviewed - Diego pointed out that documentation of new
tree-codes was missing from doc/c-tree.texi. Attached is the missing doc
patch. Is it OK?

Other than that the multiple-datatypes-vectorization project is ready to be
committed, except I haven't been able to build gfortran in the last few
days - getting this error:

I assumed that this is related to the c99 issue (and
http://gcc.gnu.org/ml/gcc/2006-11/msg00054.html ?).
So my most recent bootstrapping/testing on ppc and x86 is without fortran
(I have tested it with fortran in the past).
Is it ok to commit the project this way,
or is there a way to build fortran with current mainline?
