Description seagull 2001-10-20 21:20:00 UTC 
In /usr/include/dev/usb/usb.h line 501, the definition for 
struct usb_device_info includes the following member:

   u_int8_t        class;                          /* bDeviceClass */

Since "class" is a C++ keyword, this breaks C++ sources that attempt to
#include this file.

Fix: 

Don't use 'class' as a variable name.
How-To-Repeat: Compile this with C++

#include <dev/usb/usb.h>
int main (int argc, char **argv)
{
   return 0;
}


You'll get this:

In file included from foo.cc:1:
/usr/include/dev/usb/usb.h:501: syntax error before `;'
