Problem with ELF development suite

[Jeffrey Ebert <jebert@earthlink.net>]

I recently made the big switch to ELF development. I had been running ELF
binaries for several weeks, but I was installing some new packages to support a
tape drive, so I made the plunge. Sorry about the length, but I figure that my
configuration is probably the problem so here are some excerpts from dpkg -l.

I have the following tools installed:
ii  bin86              0.1 11   Assembler and loader for kernel compilation.
ii  binutils           2.6 2    The GNU assembler and binary utilities (ELF
ii  gcc              2.7.2 5    The GNU C compiler (ELF version).
ii  ldso            1.7.14 1    The Linux dynamic linker, library and utilities
ii  make              3.74 11   GNU Make.

I am trying to compile the following source packages:
ii  source          1.2.13 7    Linux kernel source.
ii  ftape             2.03 1    QIC-117 (Floppy-tape) driver, in source code fo

I have the following library packages installed:
ii  aout-librl       2.0.3 4    GNU Readline shared and static libraries.
ii  ncurses-base    1.9.8a 4    Video terminal manipulation: Minimum set of ter

ii  ncurses3.0      1.9.8a 4    Video terminal manipulation: shared libraries
ii  libc4           4.6.27 11   The Linux C library (a.out version 4).
ii  libc5           5.2.18 1    The Linux C library version 5 (run-time librari

ii  libgdbm1         1.7.3 8    GNU dbm database routines (runtime version).
ii  libreadline2       2.0 12   GNU readline and history libraries, runtime ver

ii  xlib             3.1.2 4    XFree86 3.1.2 shared libraries

I have successfully made one ELF binary: xbench. However, I seem to be having a
problem with in-line assembly code that is present in asm/io.h.

Here are some example error messages that result from building ftape with the
ELF gcc:

The same sort of errors are spewed out of the kernel build early in the
process. 

I loaded the aout-* tools and successfully compiled the kernel and the ftape.o
module. Nonetheless, I'd like to solve this problem. Something simple?
