Compilation warnings on macOS 14.0 with Apple M2 chip

[lamjack]

Hello,

I'm experiencing some compilation warnings when installing go-callvis on macOS 14.0 (23A344) with an Apple M2 chip. I thought it might be important to report this in case it affects other users or if it could potentially lead to issues down the line.

Environment:

• macOS version: 14.0 (23A344)
• Chip: Apple M2
• Go version: (run go version and paste the output here)

Installation Command:

go install github.com/ofabry/go-callvis@latest

Warnings:

These warnings seem to point towards implicit truncation from 'int' to a one-bit wide bit-field and functions defined without prototypes, which are deprecated in current and future versions of C.

Despite these warnings, the installation completes, but I'm concerned about the potential for unexpected behavior or compatibility issues with future versions of Go or macOS.

Is this something that can be looked into? Any guidance on whether these warnings can be safely ignored or if they will be addressed in a future update would be appreciated.

Thank you for your time and for maintaining this project!
