What's the origin of that /opt/local/include/usb.h file? It
appears to be a "system header" and most probably is not a sigrok
provided one. Which suggests that the issue is caused by some
other upstream component, and cannot get fixed by the sigrok
project.
BTW the uint8_t etc types are provided by <stdint.h> assuming
that your compiler supports C99 (or a preview of it).

Hint: A "diff" more appropriately represents what actually has
changed. See the diff(1) and patch(1) commands. Train yourself
to run diff(1) with -u or -c for human readable output. Or just
use git(1) when you already got the sandbox on your machine.
What exactly is the issue here? Can you expand? Is it a problem
when warnings are considered an error? Which are the warnings
that trouble you, and would it be more appropriate or helpful to
fix those warnings instead of just silencing the compiler? After
all the compiler tries to tell you something when it emits a
warning. :)
