Cygwin support lacking #2278
Description
To Reproduce
I followed the steps on the quickstart section of the readme file. Building seems to be fine on my Windows 10 Enterprise within Cygwin. When running, I get a segfault which is listed below. I have reviewed the basic.md instructions, I don't understand why the parser::iterate() didn't work. I'm not sure if it is a bug in the code, non-compatible configuration [despite being able to build], or if I have missed something. Please advise.
simjson release
As per the instruction the wget is on the master branch. Note: using the v3.10.1 release doesn't seem to make a difference.
