@ccurtsinger is this straightforward to restore?
As per the comment above gettid() isn't available in glibc versions < 2.3
I worked around that with this change
$ git diff

Commit f7b60a68d36f026c4054bdf4c52463b63832fa1b deleted libcoz/ccutil/thread.h, which defined gettid() for glibc versions not defining it. The result is an undeclared gettid() when compiling with glibc pre-2.30.
