template bug on HPUX 11 in GCC 3.0 branch

[Rob Savoye <rob at welcomehome dot org>]

  I was testing the gcc 3.0 branch the other day on HPUX 11.00, and found that
an old bug in GCC 2.95.2 and 2.95.3 is still there. (it's also in the GNUPro 
branch as well) I'm trying this on hppa2.0w-hp-hpux11.00. (a PA-RISC based
J5600) This test case reproduces the problem. Compile main.c and sub.c, and
when executed, it should print:

push count 9
push count 10

  On HPUX 11.00, it prints 9 twice. What seems to be happening is that the 
static variable instantiated in stack::push() is getting multiple copies,
one for each object file. It should only get one copy. This works on Solaris
and Linux. It'd be nice if this could get fixed before the real release...
