Update used double-conversion?

[catap]

Good day,

I had created a port for ejabberd for OpenBSD and during building the port was discovered that ejabberd fails on i386 with error:

===> Compiling /pobj/ejabberd-24.10/ejabberd-24.10/c_src/double-conversion/strtod.cc

static const int kExactPowersOfTenSize = ARRAY_SIZE(exact_powers_of_ten);
                 ^
3 errors generated.

This error was had come from jiffy's embeded version of double-conversion which was fixed a while ago here: https://github.com/google/double-conversion/pull/123

Here I'm asking: isn't it a good idea to update double-conversion?
