Subject: Error out at runtime when seteuid/setresuid or setegid/setresgid are not
X-Git-Tag: tdb-1.1.5~958^2~1

Error out at runtime when seteuid/setresuid or setegid/setresgid are not
available. This means it's possible to compile libreplace when these
functions are not available and use it, as long as this particular
function is not used.
