Attiny85 and Servo library

I'm using SpenceKonde's ATTinyCore libraries, and I'm getting an error when I try to compile a bare minimum sketch that only includes the Servo.h library. The errors are not there when I compile for something official like an Uno.

I've looked at the ATTinyCore docs here: GitHub - SpenceKonde/ATTinyCore: Arduino core for ATtiny 1634, 828, x313, x4, x41, x5, x61, x7 and x8

and the ATTiny85 subsection here: ATTinyCore/ATtiny_x5.md at OldMaster---DO-NOT-SUBMIT-PRs-here-Use-2.0.0-dev · SpenceKonde/ATTinyCore · GitHub

and Servo is mentioned, but nothing says it cannot be used for this chip. Does the library not work with the '85?

It is currently not supported. There is an open issue to fix this - it's one of the issues I have really wanted to sort out for a very long time - it's somewhat tricky to achieve, because working with the weird timer on the x5 and x61 series tinies is somewhat challenging.

There are some other (non-core-associated) libraries that provide timer support on the x5, though.

My goal as with the Unified Wire/SPI libraries is to offer an identical API for all the tinies - I've done a much worse job than I had always hoped here.
