description:
remove PCC specific definitions for __packed, __aligned and __section
which result in a _Pragma() usage.  I don't think this ever worked,
as you can't concatenate string literals in this way.  A warning
would have been produced, but until recently did not result in an
error condition so this was overlooked. Use __attribute__ instead as
this is supported by PCC.
