ENCODING OF LITERALS
If the environment variable UGCC_LANG is set it defines the OS locale for parsing 
and thereby defines the encoding that is used to interpret the literals in the source file

CHANGES TO ORIGINAL GCC
- all changes are marked with 'UTF_CHAR'
- accept 'u','U' preceding literals analogue to 'L' for wide character
- use mbtowc to build wide string literals from source code
- write Unicode literals with appropriate width and appropriate type
- extend string concatenation to handle new literals
- extend special type checks for string literals
