RE:building emacs 21.3 on powerpc-ibm-aix5.2.0.0

[Brent S Elmer]

The problem is in the file configure.in.  As you can see in the configure
output, my system is:

checking host system type... powerpc-ibm-aix5.2.0.0

however the aix lines in configure.in don't cover this host correctly as
can be seen by this clip from configure.in.

rs6000-ibm-aix3.1* | powerpc-ibm-aix3.1*  )
    machine=ibmrs6000 opsys=aix3-1
  ;;
  rs6000-ibm-aix3.2.5 | powerpc-ibm-aix3.2.5 )
    machine=ibmrs6000 opsys=aix3-2-5
  ;;
  rs6000-ibm-aix4.1* | powerpc-ibm-aix4.1*  )
    machine=ibmrs6000 opsys=aix4-1
  ;;
  rs6000-ibm-aix4.2* | powerpc-ibm-aix4.2*  )
    machine=ibmrs6000 opsys=aix4-2
  ;;
  rs6000-ibm-aix5.1* | powerpc-ibm-aix5.1*  )
    machine=ibmrs6000 opsys=aix4-2
  ;;
  rs6000-ibm-aix4.0* | powerpc-ibm-aix4.0*  )
    machine=ibmrs6000 opsys=aix4
  ;;
  rs6000-ibm-aix4* | powerpc-ibm-aix4*  )
    machine=ibmrs6000 opsys=aix4-1
  ;;
  rs6000-ibm-aix* | powerpc-ibm-aix* )
    machine=ibmrs6000 opsys=aix3-2
  ;;

configure uses the line rs6000-ibm-aic* | powerpc-ibm-aix* as can be seen
in the configure output:

Configured for `powerpc-ibm-aix5.2.0.0'.

  Where should the build process find the source code?
/u3/brente/g1/emacs-21.3
  What operating system and machine description files should Emacs use?
        `s/aix3-2.h' and `m/ibmrs6000.h'


This target doesn't work.  To correct the problem, I used the following to
get emacs to build:

./configure --host=powerpc-ibm-aix5.1.0.0

which you can see from configure.in picks up the following:


 rs6000-ibm-aix5.1* | powerpc-ibm-aix5.1*  )
    machine=ibmrs6000 opsys=aix4-2
