Hello Ashvith,

I'd like to give my feedback on this patch series. I'll send an updated patch

According to its README, the unit tests are run using the built c3c with its 
compile-test subcommand: `c3c compile-test test/unit`. The `check` build phase 
needs to be replaced to run this command.

A patch sent upstream to add a proper `check` target would be good, and the 
test/ subdirectory would probably also need to be specified as part of the 
out-of-tree build.

The curl dependency should be removed, since c3c's optional dependency 
downloading functionality isn't needed in Guix.
