Maybe some of them but certainly not all.

For example to avoid filename conflicts for STL and libg++ header 
files it's necessary to rename some of them with corresponding 
changes to other files. I don't think such changes will be accepted...

Also I patched gcc/dwarf2out.c to avoid need to use BFD assembler
to get exceptions working. AS from binutils-2.9.1 built as BFD 
assembler is broken. From snapshots it works, but I think 
exceptions should work with released versions. Related patch to
dwarf2out.c sent by Laszlo Molnar (he found source of problem) 
was rejected.

But of course I'm not patching all files manually: as before 
(beginning from egcs-1.1) I use some shell script that does this
work for me. Currently I did rather big changes to this script to 
make it simpler (removed embeded patches from it to a separate 
directory tree). When I'll think I'll be ready I'll make it also available.
