Yes. Using either #pragma std-c89 or the command line option --std-c89
will disable the keywords that conflict with allowable identifiers.
However, this support is only in the compiler itself at the momement; I
still need to update the CPU specific header files to operate in either
mode and update the manual (in the next few days, hopefully).

The extended storage class keywords are now always available in a form
with leading double underscores. This should not conflict, since the
standard reserves this part of the namespace for the use of the compiler
and its libraries.
