Please show the relevant part of the configure script.  Since the
configure is generated on each user's system as part of the build, it
is hard to guess what you have there without seeing the actual code
you get.  For example, on my system, line 33322 of the configure
script is an empty line, and I see no "!=" anywhere around that.

So more data is needed to investigate this.

Thanks.
