2010-07-20glcpp: Avoid accidental token pasting in preprocessed result.Carl Worth
Consider this test case: #define EMPTY int foo = 1+EMPTY+4; The expression should compile as the sequence of tokens 1, PLUS, UNARY_POSITIVE, 4. But glcpp has been failing for this case since it results in the string "1++4" which a compiler correctly sees as a syntax error, (1, POST_INCREMENT, 4). We fix this by changing any macro with an empty definition to result in a single SPACE token rather than nothing. This then gives "1+ +4" which compiles correctly. This commit does touch up the two existing test cases which already have empty macros, (to add the space to the expected result). It also adds a new test case to exercise the above scenario.
