One line patch to add C99 UTF-8 support in identifiers to gcc

In response to FAQ

> What is the status of adding the UTF-8 support for identifier names in GCC?

and the request

> Support for actual UTF-8 in identifiers is still pending (please contribute!)

my observation is that UTF-8 in identifiers is easy to add to gcc by changing
one line in the cpp preprocessor, provided a recent version of iconv is
installed on the system.  The patch is attached and has been tested for about 6
months.  More information about this patch as well as unrelated information
about getting cilkrts to work on ARM is available at
