Due to the various number of +# minor-version numbers that can exist, and the fact that string +# comparisons are not compatible with numeric comparisons, this is not +# necessarily trivial to do in a autoconf script.

An +# empty string is the same as version 0. OP is evaluated by autoconf, not +# configure, so must be a string, not a variable. +# +# The author would like to acknowledge Guido Draheim whose advice about +# the m4_case and m4_ifvaln functions make this macro only include the +# portions necessary to perform the specific comparison specified by the +# OP argument in the final configure script. +# +# LICENSE +# +# Copyright (c) 2008 Tim Toolan <toolan@ele.uri.edu> +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved.
