test.cs
Attached test case shows a problem with mcs incorrectly handling invalid
preprocessor directives of the form:
#if DEBUG
...code...
# something not valid here
...code...
#endif
If DEBUG is not defined csc reports cs1024:
test.cs(9,3): error CS1024: Preprocessor directive expected
while mcs in that situation doesn't report any error and skips the entire block
between #if and #endif.
If DEBUG is defined, csc reports cs1024 and cs1025:
test.cs(9,3): error CS1024: Preprocessor directive expected
test.cs(9,13): error CS1025: Single-line comment or end-of-line expected
while mcs reports only cs1024:
test.cs(10,0): error CS1024: Wrong preprocessor directive
Note also that the (line, column) location is incorrect with mcs.
