I have gotten X11R5 pl 23 to compile on AIX 3.2.2 using cc.
 but the server will not run. it simplys starts and a couple seconds
 later exits. no error are displayed. 
 my defines for compile are
 -DSYSV -DAIXV3 -DSYSV_WAIT   -DMALLOC_0_RETURNS_NULL 

 
   could somewhere share some light, or maybe the ibm.cf file. 

 thanks.
