If we assume that $2 is a literal `yes' or `no', i.e., the value can be 
decided at autoconf time (rather than at configure time) it seems it 
should be possible to expand to enabled or disabled depending on the 
value of $2. I'm not sure, however, that assumption is true here. Is it? 
If so I think it should be possibe by replacing some of the shell code 
with m4 code.

Cheers,
Peter
