Nothing is wrong.  You are hitting a known bug of HP/UX make: it
wants to rebuild a target if one of its dependencies has the
same date.  This is the case here, m4.info and its source
(m4.texinfo) have the same timestamp.

% tar ztvf m4-1.4.2.tar.gz | grep doc/m4
-rw-r--r-- 501/501      112683 2004-08-21 12:29:00 m4-1.4.2/doc/m4.info
-rw-r--r-- 501/501      107606 2004-08-21 12:29:00 m4-1.4.2/doc/m4.texinfo

Possible solutions:

 - install GNU Make and use it, or

 - install Texinfo (so makeinfo works), or

 - do "touch doc/m4.info" before running "make"
