macOS Monterey Build Failure

[jmstacey]

Unable to compile on macOS Monterey 12.1 (21C52)

side note: instructions should probably be brew install gcc@9 instead of gcc@6 ?

Errors on make:

There are also a number of other Linux-specific lines of code. I guess they gave up on multi-platform. I gave up when I got to sigtimedwait().

I used <limits.h> on macOS Big Sur and it worked.
There are still errors but I think I solved that one.
