Hmm, you are right. The solaris /bin/sh is older revision of posix.

yes, it does work if executed by /bin/bash or /bin/ksh

Unfortunately, no. The /bin/sh says "bad substitution" and does not run
the script at all. I also tried
eval 'echo ${A%%1}'; echo ok
but that does not run the 'echo ok' and fails also.
I can see three possible solutions
1) use bash or ksh in the shebang line
2) rewrite the script as I gave the overview
3) declare that solaris 10 /bin/sh is not compatible with configure
script
Frankly even 3) is viable option, one just have to remember to run
'bash configure'. If everything else would work, I would be happy :)
Thank you
