# - ^as_
# M4sh's shell name space.
# - ^ac_
# Autoconf's shell name space.
# - prefix and exec_prefix
# are kept undefined (NONE) until AC_OUTPUT which then sets them to
# `/usr/local' and `${prefix}' for make.
# - (host|build|target)(_(alias|cpu|vendor|os))?
# Set by AC_CANONICAL_(HOST|BUILD|TARGET).
# - cross_compiling
# Set by AC_INIT.
# - interpval
# Set by AC_SYS_INTERPRETER.

# AT_CONFIG_CMP(VAR-FILE-A, VAR-FILE-B)
# -------------------------------------
# Check the outcomes of two configure runs for equality by comparing dumps of
# their shell variables. VAR-FILE-A and VAR-FILE-B are two `set'-style shell
# variable space dumps.
#
# We permit variance between runs in the following shell variables:
# - ^as_
# M4sh's shell name space.
# - ^ac_, excluding ^ac_cv_
# Autoconf's private shell name space.
# - PPID [bash, zsh]
# - RANDOM [zsh]
# - SECONDS [zsh]
# - '$' [zsh]
# - argv [zsh]
# - ARGC [zsh]
#
# Furthermore, it is okay for a non-cache variable initialized to empty in one
# run to be unset in another run. This happens when, for example, cache update
# code tries a number of values in LIBS and eventually restores LIBS to its
# original value. If LIBS was previously unset, it will have become set and
# empty. (OTOH, cache variables indicate the result of the test even if they
# are empty, so we have to be strict about them.)
#
# Lines that do not look like `foo=bar' are probably latter lines of
# multiline values; trim them.
