Is the hack that is mentioned necessary or is there another solution?
This seems like it is a question more appropriate for the libtool list.

No, ${parameter:offset} and ${parameter:offset:length} are bash specific
not XSI mandated.
But we don't need bash-specific hacks.
${parameter#??} serves as a great XSI alternative to ${parameter:2},
and with a (lot) more thought, ${1:1:1} can be written without forks
and without bash-isms as:

are the day I
push upstream, the author date is still my original date of writing the
