Cygwin provides autoconf 2.69 but it's what builds the package that counts, also 
perhaps what is available in the cross-build toolchains supported by newlib for 
some platforms with limited support.

Some packages or platforms may have maintainers that are not comfortable with or 
have difficulty updating their autotools infrastructure, so that part of the 
process languishes: some packages are notorious for how old their autotools 
requirements are.

Some packages will not build if autoreconfiged, why old releases are still 
supported: autoconf/autoheader/autoreconf/autoscan/autoupdate 2.13-2.69, 
automake 1.4-1.16.
