Public bug reported:
Having a look at step 1 of "Using the Standard C++ Library", at :
http://gcc.gnu.org/onlinedocs/gcc-4.7.1/libstdc++/manual/manual/using_headers.html
it says:
<quote>
Precompiled Headers
There are three base header files that are provided. They can be used to
precompile the standard headers and extensions into binary files that
may the be used to speed compiles that use these headers.
stdc++.h
Includes all standard headers. Actual content varies depending on language
dialect.

So, on Ubuntu 12.04, with gcc-4.6-multilib (4:4.6.3-1ubuntu5) installed on an
x86_64 ,
I do:
$ echo '#include <stdc++.h>' > t.cpp
$ g++ -c t.cpp
$ g++ -c t.cpp
t.cpp:1:20: fatal error: stdc++.h: No such file or directory
compilation terminated.
So one cannot use the standard documentation for the standard C++
library with your distribution .
Evidently g++ is invoking cpp without these directories being searched :
$ find /usr/include -name 'stdc\+\+\.h'
/usr/include/c++/4.6/x86_64-linux-gnu/bits/stdc++.h
/usr/include/c++/4.6/x86_64-linux-gnu/32/bits/stdc++.h
Even though cpp purports to be searching them :
$ cpp -print-search-dirs
install: /usr/lib/gcc/x86_64-linux-gnu/4.6/
programs:

Please rectify - or do I have an installation problem ?
This machine was set up by my company IT and should have been installed from
latest Ubuntu DVD a couple of weeks ago -
it is saying all packages are updated to latest versions.
