Regarding your second solution, I think it's more elegant and

make.

With my distro hat on: this isn’t used by too many programs.

Debian Code Search returned a module of Boost. Otherwise, all apps

correctly use sysconf(_SC_SEM_VALUE_MAX) in my cursory glance.

With my gcompat hat on: yes, please don’t change it.

The current value matches glibc and while it doesn’t seem many things

use it, I would hate to have to debug those kind of corner cases in

binary blob code.
