I asked about this a whil ago, but since I didn't receive any
comments, I'm asking again.
bash's behaviour with regards to the 'set' builtin has changed
in 2.05:

This apparently lead to a broken config.cache when using bash 2.05
(not sure which version of autoconf):

What I wanted to know is whether or not this is likely to
affect current autotools (I don't have a version of bash 2.05
installed, so I can't check myself)? If so, it will need to be
fixed; if not, it is probably still worth mentioning in the
autoconf manual's section on portable shell programming.
