[PATCH] Fix detection of powerpc64 on Darwin in lib/config.guess.

[Torsten Mähne]

Hello,

I originally reported this problem to the automake bugs mailing list and was 
asked to report it further upstream:
 
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=14323

Please find attached a fix for config.guess, which corrects the detection of 
powerpc64 on Darwin (Mac OS X). The patch was done agains the config.guess 
version found in commit dc4eaab in git://git.savannah.gnu.org/automake.git. 
Explanation:


On Darwin (OS X) `uname -p' returns powerpc even if the CPU and OS are 
64-bit-capable. This problem has been already observed and resolved for the x86 
platform. The same approach works for the powerpc platform.


I observed the bug in GNU automake 1.13.1.

Best regards,

Torsten Maehne
