autoconf problem

[Michael McMahon]

Hi,

Since my latest sync of jdk8/cpu (today) I can't run configure. I get 
the following
error:

$ bash ./configure
Warning: The generated configure file contains changes not present in 
the custom generated file.
Cannot locate autoconf, unable to correct situation.
Please install autoconf and run 'bash autogen.sh' to update the 
generated files.
Error: Cannot continue

--help
Warning: The generated configure file contains changes not present in 
the custom generated file.
Cannot locate autoconf, unable to correct situation.
Please install autoconf and run 'bash autogen.sh' to update the 
generated files.
Error: Cannot continue

Now, I don't have "autoconf" installed but before I try and continue by 
installing it,
I'd like to understand more why this is happening. Any ideas?

Thanks!
Michael
