There is apparently only a single shell function in gnulib-tool which
makes use of the '!' feature. Is it really so horrible to work around
this non-POSIX instance? I suspect the patch after my signature should
do the job (I didn't get an error on the Solaris 9 box and the hello CVS
tree.)
That said, if you would rather have hard tests for ! support and maybe
even test for GNU sort in the script (there is a comment that it is
needed), I would not complain.
The cvs project sanity.sh script does tries to find versions of tools
that are on the machine to do the job that needs to be done. So, even if
the PATH is /usr/bin:/usr/local/bin and /usr/local/bin has GNU stuff, we
have a chance of finding the right thing.
Testing that the $SORT supports the -g switch would probably be
sufficient which is used to set the autoconf_minversion ...

Hmmm... is it worth the effort to try to make GNULIB easier to use?
