I have some code that works for a 3.5, but I cant get it to compile for a Teensy++ 2.0. Am I doing something wrong, or does the ++ 2.0 not support something that the 3.5 does??

Error
Code: 
test_multi_debounce: In function 'void check_switches()':
test_multi_debounce:86: warning: comparison between signed and unsigned integer expressions 
   if (millis() < lasttime) {
       ~~~~~~~~~^~~~~~~~~~
test_multi_debounce:90: warning: comparison between signed and unsigned integer expressions 
   if ((lasttime + DEBOUNCE) > millis()) {
       ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~

Library #include "TeensyThreads.h" certainly will not work on an AVR processor Teensy 2.x.

That uses Code specific to the 32 bit ARM processors.
 
Teensythreads contains a fair bit of assembler code which is specific to the ARM architecture whereas the Teensy++2 is an AVR.
From the readme.md:
Teensy Threading Library implements preemptive threads for the Teensy 3 & 4
