Still trying on a 2.4.18 kernel.  I went and retrieved the 
ftape-4.x-2002_08_02 tarball, it being the latest in the unstable dir.  I'm 
getting a lot farther, but still have failure.

I do NOT have CONFIG_ZFT_OBSOLETE defined in MCONFIG.  I guess I need to make 
sure I'm not using CONFIG_ZFT_COMPRESSOR and CONFIG_ZFT_COMPRESSOR_MODULE? 
Since there are no previous tapes, I don't have to worry about backward 
compatibility.

I think the part that's getting me into trouble here is in include/linux/zftape.h:

#ifndef CONFIG_ZFT_OBSOLETE
# define ZFT_MINOR_OP_MASK 0
#else

/* NOTE: all of these bits are considered OBSOLETE. In-kernel
  * compression isn't supported any longer, and the "raw mode" stuff is
  * controlled using an ioctl
  */
# define ZFT_Q80_MODE           (1 << 3)

Since CONFIG_ZFT_OBSOLETE is not defined, but apparently the _MODULE def is, 
the compile is failing.  Is the proper thing to do to change MCONFIG so that 
DCONFIG_ZFT_COMPRESSOR_MODULE and CONFIG_ZFT_COMPRESSOR are always undef?

TIA,
Kevin
