Failed compile due to security_context_t and friends on CentOS 5

Failed compile due to security_context_t and friends on CentOS 5

[Jeffrey Walton]

Hi Everyone,

I'm building Emacs 24.5 from sources on CentOS 5. It looks like the
build is failing as shown below.

The config.log is too large to attach to an email or drop on pastebin.
I can provide it if anyone is interested.

Does anyone know how to avoid the build failures for this platform?

Thanks in advance.

(As an aside, your distribution was EOL'd 9 months ago:

Adding "--without-selinux" to the configure options is probably the
easiest fix.
