    How do you get GCC to find these headers?  If you're using -isystem or something alike, be it in the command line or in the specs file, this will get GCC to handle the headers as C sources.

>Description:
We have the same problem reported on #3866, with the following addition:

C++ included headers, located outside current directory are evaluated as C headers.

If we include a .hpp file in a C++ source file (either with <> or "") and they are outside, we receive the lots of errors like:
In file included from smalldate.cpp:4:
/opt/tuxedo/include/smalldate.hpp:29: declaration of C function `const 
   middleware::smalldate middleware::operator-(const middleware::smalldate&, 
   int)' conflicts with
/opt/tuxedo/include/smalldate.hpp:27: previous declaration `const int 
   middleware::operator-(const middleware::smalldate&, const 
   middleware::smalldate&)' here

Actually, these are overloaded C++ functions ...
>How-To-Repeat:
cat> test.hpp
int test(int i);
int test(float f);
ctrl-D
mv test.hpp <somewhere on the C++ include path>
cat> test.cpp
#include <test.hpp>
int main() {
 test(0);
}
ctrl-D
g++ -c test.cpp
