here is what I have in the subordinate configure.in
# ac_use_included_regex is NOT cached, so we have to duplicate the
# logic of src/glm4/regex.m4!
case $with_included_regex in
yes|no) ac_use_included_regex=$with_included_regex ;;
'') case $gl_cv_func_re_compile_pattern_working in
yes) ac_use_included_regex=no;;
no) ac_use_included_regex=yes;;
esac ;;
esac
is this cheap?
and, more importantly, is this correct?!
note also that gl_cv_func_re_compile_pattern_working is not found by
"grep -i regex" ;-(
