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:
[EMAIL PROTECTED]: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:
[EMAIL PROTECTED]:bviren> g++-2.95 blah.cc
[EMAIL PROTECTED]:bviren> g++-2.95 -I/usr/include blah.cc
[EMAIL PROTECTED]:bviren> g++-3.0 blah.cc
[EMAIL PROTECTED]:bviren> g++-3.0 -I/usr/include blah.cc

Yes, that's right. It's not a bug, however. That's what -I is
documented to do; it moves a direcvtory to the head of the include
chain if it's already been specified.
Don't do this. Any script which emits -I/usr/include or makefile that
assumes it is broken.
