error compiling qmail Suse 6.4

[Schwarz Hans-Juergen]

Hello all,
I just tried to compile qmail on Suse 6.4. It stopt  on
./compile sig-alarm.c with the following message:

In file included from /usr/include/signal.h:300,
                from sig_alarm.c:1:
/usr/include/bits/sigcontext.h:28: asm/sigcontext.h: No such file or directory
make: *** [sig_alarm.o] Error 1

the file sigcontext.h is in that directory but maybe its something
wrong with it? Do you got any ideas?

Thank you very much
Hans-Juergen
