By formatting things like the above, without any '(())', then indent is
happy.  I run indent on the idn2.h and it looks like the above without
any INDENT-OFF.  If I included the '(())' part, then just like you I had
issues getting indent to behave.  The conditional part is unrelated to
the indent issue, but I can see that my recommendation was unclear.
