hmm - that might be due to the server-side compression fix (will see).

(The suggested filename - which you can edit - depends on how lynx
sees the remote filename).

By default, the configure script tries to find how to compile the program
to support large (>2Gb) files:

  --disable-largefile     omit support for large files

Doing that requires it to test-compile the more likely possibilities.
For some of those, the header-files will declare symbols such as gzopen64
which don't happen to be in your actual libraries:

no (and for largefile support, it's been quite a while since I made changes)
