"the `sigstack' function is dangerous"

[dwicks]

Greetings;

I am trying to install from m4-1.4.tar.gz on linux for S390, kernel 2.4.2.

I run:

     ./configure --prefix=/usr
     make

and get message:

     stackovf.o: In function `setup_stackovf_trap':
     /root/m4-1.4/src/stackovf.c:255: the `sigstack' function is dangerous.
`sigaltstack'       should be used instead.

When I run  make check  I get several messages:

     m4: sigstack: Bad address

starting at:

     make[1]: Leaving directory `/root/m4-1.4/examples'
     cd checks && make check
     make[1]: Entering directory `/root/m4-1.4/checks'
     PATH=`pwd`/../src:$PATH; export PATH; \
     cd . && ./check-them *[0-9][0-9].*
 >>  m4: sigstack: Bad address
     Checking 01.define
     ../doc/m4.texinfo:939: Origin of test

If I then do a  make install  anyway then do   m4 --help  I also get

     m4: sigstack: Bad address


Any suggestions or information would be greatly appreciated!

Dennis
