Problems compiling Cipe 1.5.4 on kernel 2.4.21 (Debian)

[Fabio Muzzi <liste,AT,kurgan,DOT,org>]

Hello cipe-l,

I  have  compiled  and  use  cipe successfully lots of times, but now,
trying  to  compile  cipe  for  a  2.4.21  kernel  (which  I have also
compiled from source) I get the following errors:

make[1]: Entering directory `/usr/src/cipe-1.5.4/2.4.21mppe1-i386-cb'

make[1]: Leaving directory `/usr/src/cipe-1.5.4/2.4.21mppe1-i386-cb'
make: *** [all] Error 2

I  have  tried Googling for it, I have searched the cipe mailing list,
but found nothing at all.

Any idea on how to make it work?
