It appears that something is wrong with compiling steps of giggle, many `/usr/bin/ld: ../obj/leaf.o:(.bss+0xe0): multiple definition of 'cache'; /tmp/ccMqGR06.o:(.bss+0x2c0): first defined here` type errors. Output of `make` in src: [before.log](https://github.com/ryanlayer/giggle/files/9618791/before.log)...

added labelcolor variable to Garc object
