The trade-off is a slightly repetitive sed script.

string for more reliable failure. Wrap the entire test that
causes the broken Solaris printf to dump core, in a subshell,
so the segmentation fault message is reliably suppressed.
Fix shell expansion errors by using /usr/ucb/echo always;
avoid an error on systems without it by another subshell.
Avoid m4 expansion of `$1'. Set the zeroth argument of the
subshell-$as_echo to `as_echo', for better error message.

(_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,

eliminating much of the earlier complexity, while adding some
new complexity. Only expand the substitution templates at
configure time, for smaller configure script size. If
_AC_SUBST_FILES are used, test 'awk' for working getline support
at config.status time. If absent, interpolate through the
shell. The awk script was written with much help
from Paolo Bonzini and Paul Eggert.
