Re: [PATCH 2/6] c: Turn int-conversion warnings into permerrors

[Patrick O'Neill]

Hi Juzhe,

I can confirm the failure on Newlib.
I'm not seeing any issues on glibc 2.37.
I haven't tried to build musl.
Since this patch promotes warnings to errors breakages were probably 
expected.
The fix may require changes to newlib to remove the errors.
I've hacked together a series of patches on top of newlib 4.3.0 that 
resolves these issues (but I think they'd need more work to be 
upstream-able):
https://github.com/patrick-rivos/riscv-gnu-toolchain/tree/35d8e8c486bd2f6e3e2e673db8d2b979309a6de4/fixups/newlib

@Thomas @Florian am I right in assuming that breakages were expected/the 
fix should come from fixing the warnings?

Thanks,
Patrick
