Here's a first try. One thing I don't like about it is the fact that
the generated info file loses the capitalization information. Another
might be that Autoconf does not want to lock in to exporting all these
variables from this one macro -- maybe rather add something like this
and document it as providing the variables?
# AS_CR_VARIABLES
# ---------------
# Define useful character sets
m4_defun([AS_CR_VARIABLES],
[AS_REQUIRE([_AS_CR_PREPARE])dnl
])
