Although you can specify -I options to make the preprocessor search the g++-v3/ext.....

This is wrong, because <ext/memory> will get loaded instead of <memory>, and <ext/memory> does not include  ../memory
Also, note that other files (ext/algorithm, ext/functional, ext/iterator, ext/numeric) suffer for a similar problem: for example, <ext/algorithm> include <algorithm>, and this will never be found with -I.../ext
>How-To-Repeat:
g++ -c -Igcc_include_path/g++-v3/ext pippo.C
>Fix:
a) fix the doc imposing the use of #include <ext/....>
b) rename ext/memory (and the other files)
c) Is there a way to include "../memory" if and only if ext/ is in the include search path?
