+/* This test case contains a large number of syntactic errors. We
+ believe the intent of the test is that the compiler simply not
+ crash. The set of error messages reported is different when the C
+ parser is generated with bison 1.50 than 1.35. It is not worth
+ attempting to prevent this. Instead, we use a single dg-error with
+ a regexp that will match _all_ the errors indiscriminately. The
+ old error/warning/etc markers are kept around for reference, but
+ disabled.

+ Revisit after new (recursive descent) parser is implemented for C.
