I am trying to set up a small number of global variables in using Hi-Tech's
PICC product.  I am presently using the format provided in the K&R C book
(ANSI), 2nd Ed,  page 32 and I am still getting this warning:

c:\pic\picctest\picctest.c: 31: external declaration inside function (warning)

The PICC manual only mentions the extern keyword in association with
assembler files & integrating them with C code.  The K&R examples seem to
imply that using extern within a function is perfectly valid, and I really
can't get a picture on how PICC likes to handle them, as their example
lines are stand-alone, aren't put into sample code fragments.

Is there another way to make global variables exclusively using C code?

Jeff
