g++ bug in version 2.95.2

Bug Report for g++ 2.95.2
-------------------------
The following transcript shows a compilation error of a 
simple program under HPUX10.2 for g++ version 2.95.2.  It
compiles cleanly under SunOS 5.5.1 using the same version
of g++ (2.95.2).  Note: compiling under g++ 2.8.1 gives
the same error for HPUX10.2 and correctly compiles on
Solaris.

/usr/include/sys/time.h:337: `extern' can only be specified for objects and 
functions





The statement that it's flagging the error on (line 337 of 
/usr/include/sys/time.h) is shown below

extern struct sigevent;

This looks like a bad extern statement to me since there is no
variable name, just the structure tag.

Is this a bug with gcc or the include files for HPUX?  Is something
funny going on in the preprocessor?  I'm curious
as to why there seems to be very little information about this 
error (in bug reports, in the FAQ, etc) even though it seems like
it's been around for a bit and must have been seen elsewhere?

Am I using the standard C++ notation wrong?  Should I be using
the libstdc++-2.90.8 module.  If so, why does it compile on Solaris
but not HPUX?  Is that just a coincidence?  It seems like I must be
doing something wrong but I can't find out where.
