Configure.in migration facility

[John Poltorak]

I understand that Autoconf v2.50 does not work with a number of older apps 
because it is not backwardly compatible with v2.13.

To avoid needing two versions of Autoconf installed, is there anything 
like a migration facility which would convert old configure.in files to a 
format suitable for v2.50? Or alternatively, will v2.50+ be updated to 
provide backward compatibility?
