Niah? I don't understand. Are you telling us that your host does not

This is not good, as we don't mean to pass the new PATH to conftest,
rather we want to have the shell change its own PATH, and *then* to
look for conftest in it.
The explanation, just like the truth, is elsewhere :)
Could you please try to explore this into the details? I suppose you
are referring to Bash under DJGPP, right?
In particular, I'm just understanding that we may have a problem if
`pwd` returns something with : in it, we might run into false
positives in some cases. This is just my imagination as I don't run
this system, but suppose you have pwd = c:/my/autoconf-dir.
Then you end up with PATH=.;c:/my/autoconf-dir. Then *if* splitting
is performed on `:', you get `.;c' (fails), and then
`/my/autoconf-dir'. I have no idea whether on such platform
`/my/autoconf-dir' works, but I wouldn't surprised. It would explain
what you observed.
Therefore I tend to think I've been stupid choosing .;`pwd`. Rather,
sane thinking would have suggested `.;.'. Could you try to see if I
make sense, and if it fixes the issue?
