Actually it appears that nothing has changed.

autoconf relies on LINENO to distinguish between dash and bash.
Because dash has supported LINENO for years, this causes massive
breakage because autoconf then goes on to rely on a non-POSIX
echo with dash, which causes backslashes to be lost.

Debian works around this by disabling LINENO in dash.

So it's a bug in autoconf that should be fixed there.
