Package: g++-3.0
Version: 3.0-4

Hello,

This bug report may need to be redirected to a different package
(cpp-3.0 or libstdc++3-dev).

Adding "-I/usr/include" to the compile line of g++-3.0 can cause
system headers in /usr/include to *not* be found.  This is due to the
use of #include_next inside /usr/include/g++-v3/bits headers.  This
directive causes the CPP to check for the file in any directories
after the current one in the list.  Explicitly adding -I/usr/include
evidently removes it from the list of internal directories to check.

The following code will trigger this problem:

bviren@minos:bviren> cat blah.cc
#include <iosfwd>
int main (int argc, char *argv[])
{
    return 0;
} // end of main()

In the next 4 commands, the first 3 succeed, the last fails:

bviren@minos:bviren> g++-2.95 blah.cc
bviren@minos:bviren> g++-2.95 -I/usr/include blah.cc
bviren@minos:bviren> g++-3.0  blah.cc
bviren@minos:bviren> g++-3.0 -I/usr/include blah.cc
