Disregard. Compiler does not know that these will be not used.
Besides these are warnings and have nothing to do with the stuff
below.

You triggered a real compiler bug.

The difference is that I replaced my compilers quite a few times
in between and currently my main compiler is gcc-2.95.2.

If you plan to use em86 with 2.2.13 you want anyway to take
a contents of a directory /usr/src/linux/arch/alpha/math-emu
from 2.2.11 and replace with it what is in 2.2.13 or em86 will NOT work.
Don't use 2.2.10 for a replacement code but 2.2.11 with 2.2.13 is ok.

If math-emu from 2.2.11 will give an indigestion to your compiler
version I have no idea. Which one is that anyway? egcs-1.0.3?
Note that in order to use 2.2 kernels with 5.2 distribution you have
to update at least some programs/packages. A minimum set is
available in 5.2 updates and clearly marked as such.
