I really have no idea what's wrong here. I can't spot any errors here either.

Well, me neither. Autoreconf somehow pollutes the configure file with some parts of the above message, so it looks like this:

*fine-looking code*
Some influential environment variables:

When I'm trying to run the script it obviously not working. I've tried to delete the plain text parts but it just gave me more syntax errors. I'm new to the linux, and I'm not really familiar with bash scripting, so any help would be appreciated. I've also attached the generated script in case someone will manage to find possible solutions
