I am working on a linux (v 2.4.20) based powerpc(8260) board. During
development of an application program I planned to use real time
signals(SIGRTMIN to SIGRTMAX) for interprocess communication. On giving
the command 'kill -l' on the terminal window of ppc linux it displayed
only 32 signals while giving the same command on an Intel based Linux PC
(same kernel version) showed all 64 signals.
Anyone having idea whether these signals are present in powerpc Linux
kernal v 2.4.20 ?

See linux/include/asm-xxx/signal.h in your kernel tree, where xxx is the
specific arch you are interested in.
You will see definitions for a series of _NSIG macros. These define the
number of available signals and the byte size of the signal mask data
type. The stuff at the bottom is educational as well. You can then
follow those defines into other header files as needed.
Happy hacking,
