Nowadays with 3.x version of the library the functions are defined in core_cm3.h and are named:

__disable_irq();

__enable_irq();

Short info about the functionality can be found in CMSIS_Core.htm document (provided with the library). More info on page 18-19 in the PM0056 doc. (15491.pdf manual april 2009 version).

Best regards,
