#define foo(x) success
foo(argument (with,embedded , commas) -- tricky)
Add support for commas within parenthesized groups in function arguments. The specification says that commas within a parenthesized group, (that's not a function-like macro invocation), are passed through literally and not considered argument separators in any outer macro invocation. Add support and a test for this case. This support makes a third occurrence of the same "FUNC_MACRO (" shift/reduce conflict appear, so expect that. This change does introduce a fairly large copy/paste block in the grammar which is unfortunate. Perhaps if I were more clever I'd find a way to share the common pieces between argument and argument_or_comma. 2010-05-20 08:42:02 -07:00			`#define foo(x) success`
