Hi Salil Sirotia,

Welcome to RTEMS Organization. I would like to suggest you to go
through the POSIX Compliance doc:
https://docs.rtems.org/branches/master/posix-compliance/

For this project, You need to build newlib-cygwin. Here you can find
newlib-cygwin building process:

https://posix4rtemsandnewlib.wordpress.com/2017/07/22/newlib-buiding-process/

It would be good if you have Knowledge of BSP specific methods and
reentrant version of methods. You can go through BSP Development doc
to get some understanding of BSP specific methods.

@gedare/@Joel correct me if I am wrong.

Any comments and suggestions from others would be greatly appreciated.

Thanks & Regards,
Aditya Upadhyay
