Replace POSIX usleep() API with rte API.
Add a new macro for the access() API as the original function

Add extra cflags '-fno-asynchronous-unwind-tables'

Fyi, caught at the UNH lab:

I suppose this is because "-fno-asynchronous-unwind-tables" is not
passed to the base driver cflags.
Bonus question: should we make this workaround global for mingw compilation?
Thanks for the log. We will send a fix by passing the cflag to the base
driver in v2.
However, I am not able to reproduce this error on my system.
I tried using the same version as UNH lab has: gcc 8.1.0 "gcc
(x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0"
