little anoyance with configure

That would appear to be this call:

pgac_txt=`echo $pgac_var | tr '_' '-'`

(four lines from the bottom of configure) But I don't see how this
contradicts the correct usage synopses offered by the error output.

Second thought ... it's interpreting the '-' as an option? Does this
work:

... | tr 'a_b' 'a-b'

?

Doesn't that do something entirely different? The original purpose was
to convert underscores to hyphens, but it's doing something else
entirely.

$ echo test_string | tr 'a_b' 'a-b'
testbstring

On my system I need to at least escape the hyphen again:

$ echo test_string | tr 'a_b' 'a\-b'
test-string

Character classes didn't do it for me: [_] -> [-]

Have a nice day,

Would not this be a simple solution? And configure is already littered
with uses of sed.

sed 's/_/-/g'

Hm. How about
tr 'x_' 'x-'

Good idea --- that's actually the only use of tr in the whole script,
so using sed gets rid of a dependency. (I wonder if the autoconf boys
deliberately avoid tr because they know about portability issues...)
