Hi Jeff, Anders,
I applied the patch and ran the build. Everything worked great.
Thanks,
Keith

Hi Anders/Keith,
The patch should instead be setting _READ_WRITE_RETURN_TYPE in newlib/libc/include/sys/config.h to ssize_t for m68k since the io-read.c code has been specifying ssize_t for quite a while now.
Please try the attached patch for newlib and let me know if there are any issues.

FWIW, this patch fixed my build problems.
