Version of OpenTTD

I'm using master 9d5dd89

Expected result

After cloning the repo and typing ./config in the terminal the expected result is to have a successful configuration.

Actual result

Got some errors complaining about the syntax of the config file:

s@!!CC_HOST!!@gcc@g; ...": bad flag in substitute command: '.'

Steps to reproduce

1. Install OpenSSL using brew
2. Clone the latest version of OpenTTD and try to configure it

If you do that homebrew will add an "@" symbol after OpenSSL to separate the name of the package from the version. That will break the config file because it will get confused with the "@" used in the config file.

How to fix it for good

My idea is to escape the strings you're getting from the environment, so you have control over the input strings so they don't interact with the special characters.

How to fix it in a hacky way

Go to your config.lib file, find the line that contains s@!!LDFLAGS!!@$T_LDFLAGS@g; and substitute the "@"s for something else like s^!!LDFLAGS!!^$T_LDFLAGS^g; . Now it works.
