ICE in gcc 2.95.2

[Mo McKinlay <mmckinlay at gnu dot org>]

I have to say, this is the first time I've come across an ICE in 2.95.2
when compiling plain ol' C - a testament to GCC's stability if nothing
else.

GCC is:

Reading specs from /usr/lib/gcc-lib/i686-pc-linux-gnu/2.95.2/specs
gcc version 2.95.2 19991024 (release)

Anyway, this code causes an ICE with 2.95.2 on both:

Linux sphere.man.uk.ekto.org 2.0.36 #1 Tue Oct 13 22:17:11 EDT 1998 i686
unknown

(RedHat 5.2, AMD M-II 233, 64 meg of memory)

and on

Linux box 2.2.13 #1 Tue Oct 13 22:17:11 EDT 1998 i686 unknown

(Slackware 7.0, AMD Athlon 700, 128 meg of memory)

The included outputs are both from the former machine, although a copy of
them from the latter can be provided, if needs-be.

The makefile runs:

(There's an error in the soures, I know, but it shouldn't cause an ICE :)
