Interrupt handling with the Teensy 3.1

I am working on using a Teensy 3.1 to talk to several peripherals which will start their conversations with interrupts. Apparently all pins on the Teensy will support interrupts. However, I found some commentary from the early days of Teensy 3.1 indicating that the nointerrupts() and interrupts() functions generally available for the Arduino family were not supported by the Teensy 3.1.

Since those comments were from a couple yaeas back, I would like to know if anyone has more current data on the subject. Thanks in advance for any help.
