Generally speaking, the Autoconf philosphy is to not bother checking
version numbers, since they are often misleading and are a maintenance
nightmare. Instead, test for tool capabilities. For example, suppose
you want to use the 'restrict' keyword if available. Don't check the
compiler's version number; instead, compile a little program that uses
'restrict', and see whether the compilation succeeds.

It could be done, yes. However it is a bit much to copy 'sed's source
code around.
