Yes! Spot on! :-)
No 5. is the key. The problem is how best to do it.

You understand correctly. I just don't think your solution would work coz my
understanding of the gcc build process is:
- during the build, gcc's private include dir is born
- gcc's own private headers are dumped there
- the result of the fixincldes process i.e. the fixed headers are dumped
there as well.
The include dir now exists and now contains everything it needs. Patching
the makefile after the build will not change the contents of the include dir
coz fixincludes has already been run. make install just installs the whole
Thats my theory anyway. All this talk is utterly useless until somebody
tests it :-)
