template static members on BSD, HPUX in 2.95.1

["Stephen F. Booth" <sbooth at saaba dot lmi dot net>]

Hi,

In trying to compile cgicc-3.1 on BSD and HP/UX, we've run into some
problems that I believe are related to static data members in template
classes.

On an i386-unknown-freebsd2.2.8 system running gcc-2.95.1, a simple test
program cannot be linked, while the same program works correctly with
gcc-2.95.1 on Solaris and Linux.  I know this sounds like a linker error
at first glance, but I don't believe so since the compiler is not
producing object code for the static member.

I've attached testT.ii to this message, compressed with bzip2.
