Details:

The AX_PREFIX_CONFIG_H macro doesn't work with dash, the bug is already noted
in the source file. As of autoconf 2.62, AS_ECHO can be used to print strings
that may contain backslashes or look like options. This patch updates
AX_PREFIX_CONFIG_H to use it.

The comment in the source file refers to $ECHO from libtool, but this
requires libtool.m4 which is not part of autoconf, and AS_ECHO is. On the
other hand, libtool.m4 (at least the one on my system) only requires autoconf
2.58 or higher, so depending on how much you value compatibility with older
autoconf versions, that may be a better choice.
