Jim,

First of all, I suggest you get some current documentation and an
up to date copy of MPASM or, better yet, MPLAB.  There will be a
more appropriate include file such as p16c74.inc.

PIE1 and PIE2 are in the upper ram page adn the page bit needs to
be set to access these two registers.  This will not, however,
suppress the warning message.  Try this:

   clrf    PIE1 ^ h'7f'
   clrf    PIE2 ^ h'7f'

Are you sure you are getting a warning on the T1CON line?  This
register is at address h'10' in the lower ram page and should not
produce an assembler warning.
