[OEvgeny]

A small fix for the built-in awk strcmp check I found while wandering through the sources.

Thank you!

I'm sorry this project does not accept anonymous contributions, as mentioned in CONTRIBUTING.md. I've removed this merge. It's important to me that when people see this project and look at the git log that they know real people wrote it. I don't believe there's any legitimate reason to do STEM anonymously unless you're Satoshi Nakamoto and even he ended up regretting it. Because I made a mistake in hastily merging this I'm going to need to remove you from the project unless you're open to fixing this, since contributor status was incorrectly granted which would allow you to bypass this review process in the future. Please reach out to jtunney@gmail.com and we'll discuss further.

@jart contacted by email, sorry for confusion. I thought sharing my name is enough, committed the charge using GitHub code spaces, so it should contain my personal info.

Anyways I'm not posting this change to gather any credit. Just thought PR is better than issue
