Bug in config.guess on AIX

[David Murphy]

In config.guess GNU config.guess (2001-09-04) there is a simple problem with identification of IBM's POWER processors.  I have checked and the problem exists in the current working archive too.

The problem is due to an extra space in a grep statement, that is grep ' POWER' instead of grep 'POWER' when determining the result of a test for which processor.

review line 510 of above config.guess

The test for processor   /usr/sbin/lsattr -El ${IBM_CPU_ID}  returns

state     enable         Processor state False
type      PowerPC_POWER3 Processor type  False
frequency 333000000      Processor Speed False

but the test
  if /usr/sbin/lsattr -El ${IBM_CPU_ID} | grep ' POWER' >/dev/null 2>&1;
then
      IBM_ARCH=rs6000
   else
      IBM_ARCH=powerpc

will return powerpc rather than rs6000.

Older version of config.guess performed grep POWER

Hence this is a simple fix to make (remove the space), with the test being easily demonstrated  by the /usr/sbin/lsattr command and running config.guess itself.

The corrected config.guess should return

rs6000-ibm-aix5.0.0.0

on the current AIX 5L platform running on a RS6000 and not the currently incorrect

powerpc-ibm-aix5.0.0.0

Please contact me if you need further details or assistance.
