>Description:
cpp reports the following error when processing a source file and using -I/usr/include (see How-To-Repeat):
In file include from /usr/local/include/g++-v3/cstring:31,
   from 1.cpp:1:
/usr/local/include/g++-v3/bits/std_cstring.h:40:25: string.h: file not found

KDE doesn't compile because of this !
>How-To-Repeat:
echo "#include <cstring>" >1.cpp
cpp 1.cpp -I/usr/include >/dev/null
>Fix:
don't know,perhaps let include_next ALWAYS search /usr/include as last directory,even if it was given with -I
