DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
shell function which also contains a command substitution causes
the shell to barf. For more details and a fix see:
<http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
Possible workaround include putting the `return' in a subshell
or calling another function to set the status.
