Thanks. In general, LINENO handling is inconsistent among shells. The presence of single vs. multi-line constructs, eval, here-docs, and shell functions cause different shells to give different values to LINENO. For more documentation on this, see: http://www.gnu.org/software/autoconf/manual/html_node/Special-Shell-Variables.html#Special-Shell-Variables and this update to the documentation source, detailing even more inconsistencies: http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=10d26aa - -- Don't work too hard, make some time for fun as well!
