Sounds like this could at least print the ";" by adding two level escapes
------
#!/bin/bash

with_auto_load_dir='$debugdir\\\;$datadir/auto-load'
escape_dir=`echo $with_auto_load_dir | sed 's/[[$]]\(datadir\|debugdir\)\>/\\\\\\\\\\\\&/g'`
echo $escape_dir

ac_define_dir=`eval echo $escape_dir`
ac_define_dir=`eval echo $ac_define_dir`
echo $ac_define_dir
------

My previous example code has a typo, the last line should be "echo $ac_define_dir", not "echo $ac_defefine_dir"
