Hello, Wouldn't it be nice if Autoconf had API versioning like Automake now does? My understanding is that recent Autoconf releases have tended to be largely compatible with each other, but there is no actual guarantee that one Autoconf version cannot be incompatible with another in minor ways.
Currently very loosely speaking there seems to be the old Autoconf 2.13 "API" and the newer Autoconf 2.5x "API". How about doing what the Automake maintainers do now and have an APIVERSION which only changes when the API does? This would require some change to the current version number system I suppose but would result in everyone knowing where they were in terms of Autoconf backward compatibility. Does this not sound attractive? Jens
