I don't really want to intervene in this debate, but: <wince>.  ksh has 
at least the unfortunate property that all file descriptors other than 
0, 1, 2 are closed before an exec, and so aren't inherited by process 
children.  Ksh seems unique in this, though it isn't listed as a 
problem in the autoconf section on shell portability issues.  It's not 
a major problem -- and may not be a problem at all for libtool -- but 
it does make some otherwise attractive idioms impossible.

Oooh yes; oh yes indeedy.  I've come to the conclusion that if your 
application builds on Tru64 and OS X, then it'll build just about 
anywhere.

All the best,

Norman
