[R-SIG-Mac] Need for `-headerpad_max_install_names` with `--enable-R-framework`

[Simon Urbanek]

Heather,

yes, please, since we cannot reproduce it, please provide your complete configure flags, full info about your macOS version, tools used (toolchain version and SDK). We are adding -Wl,-headerpad_max_install_names for libraries (see etc/Makeconf, added by configure.ac for darwin), but the binary itself has never caused issues, so I wonder what makes your system produce smaller header that won’t fit the paths.

Thanks,
Simon
