how does newlib work with rtmes?

[Ray]

What will happen after you linking newlib and ¨Cenable-newlib when compile the gcc? Do you changed gcc config and add t-rtems for msp target?
I think it should be fine to compile gcc with newlib without much change. You may also check newlib\libc\machine\ to see if anything you need to add for MSP. (But I think it is not necessary)
And you have to keep in mind that try not make a new newlib for MSP. It is better to use the newlib(newlib-1.15.0) original version. Make a patch if you need, but do not create a separate newlib for msp. Because it will made it hard to maintain a separate newlibc for MSP. Newlibc full bundle will not add much overhead to the systems because RTEMS only link in the lib/func needed for your app.
BTW, RTEMS can run without libc for minium.exe if you do not include fs.
