<snip>
I have done this with a patch to the gcc4/Makefile. This is a 
sledgehammer as the gcc build tree appears to use the old format in many 
places.

replacing the patch lines with

+  cd $(SRCORIGDIR)/gcc-trunk && find -regex ".*\.\(c\|C\|h\)" -not 
-path '^\.'  -type f  -exec sed -i 's/__FUNCTION__/__func__/g' {} \;

keeps out of the svn area.

modified patcher for Makefile enclosed
