Compile-time warnings/errors (gcc 2.95.3 kernel 2.4.5)

[VDA]

Warnings from (almost) full kernel compilation
(most thing are compiled as modules)
There is one compile-time error in ixj.c

Please feel free to mail me whether this post to lkml
is useful at all.

gcc version: 2.95.3
gcc flags:
gcc -D__KERNEL__ -I/usr/src/linux-2.4.5/include
    -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer
    -fno-strict-aliasing -pipe -mpreferred-stack-boundary=2
    -march=i586
gcc flags for modules:
gcc -D__KERNEL__ -I/usr/src/linux-2.4.5/include
    -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer
    -fno-strict-aliasing -pipe -mpreferred-stack-boundary=2
    -march=i586
    -DMODULE -DMODVERSIONS
    -include /usr/src/linux-2.4.5/include/linux/modversions.h
    -c -o file.o file.c
These flags are removed from gcc lines below to unclutter things.
Sorry but I lost directory names for *.c files...
