It was due to an unfortunate oversight: some (old) non-inline assembler code
was surrounded by #ifndef __GNUC__ [ Thx for the tip, Igor! ], since with gcc
we use a (better) inline assembler.

But my recent kernel patches (uniform interface for all kernels) require that
the corresponding symbols be properly defined in the library, in case
somebody compiles with a different compiler. In fact, compiling with a
non-gcc compiler then linking with a gcc-compiled libpari failed on many

I did not detect your problem on my machine (gcc-2.95.*) because __GNUC__ was
not passed to cpp when preprocessing .S files. It breaks with gcc3.

I have removed the spurious conditional inclusion, so it should work now.
