OSX: passes except parallel/test-tick-processor. Windows test passed (without small-icu accidentally) with only pipe/network issues. Probably I just didn't hit the right button on firewall questions.

## XXX(srl295): (or TODO)

[srl295]

thanks, refactor and removed the todo. (it's done now that there are 57 AND 55 clauses)

LGTM if CI is green

[jasnell]

@srl295 ... would you see any problem in getting this back to v4 also?

[MylesBorins]

ci: https://ci.nodejs.org/job/node-test-pull-request/2207/

If we see the same failures we are seeing on #6088 we might want to consider putting #6088 on ice until the problems are worked out in this thread (to minimize churn and checked in assets)

LGTM if CI is green

[srl295]

@jasnell no problem in getting this back to v4

@thealphanerdheadsmack that's what happened. I didn't merge badly, I just didn't reapply the changes here to tools/icu/icu-generic.gyp from #6064 into #6088. That's why #6088 was failing.

Anyways looks like CI here is green except for some unrelated arm tests.

[jbergstroem]

@srl295: Are icu versions backwards-compatible -- I mean, do you have to inspect the changelog for every release or is there some kind of versioning you can rely on?

[srl295]

@jbergstroem ICU is source-level backwards compatible. So something that compiled against 56 should be able to compile against 57, etc.

[richardlau]

Looks like this should be '## Strip out the following for ICU 57 only.'

[srl295]

Yes it should say 57.

[srl295]

I'm wondering if I should just fold this into #6088. Basically just add the two configure lines fixing the URL from this PR into #6088 and close this one.

Thoughts?

[jasnell]

+1.. perhaps keep the commits separate, however.

[srl295]

@jasnell ok, good idea. I'll implement this ticket in a separate commit

[srl295]

OK the version bump (url/hash) is now part of #6088
