           Summary: Multi-line strings not diagnosed when occurring in a
                    macro call
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: preprocessor
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: gabor dot greif at lucent dot com
                CC: gcc-bugs at gcc dot gnu dot org

Compile this snippet:

----------------------
#define FOO(X) wagga X
    FOO(("kkkk
llll"));
----------------------

In gcc-3.4 I get these errors:

foo.C:100:1: unterminated argument list invoking macro "FOO"
foo.C:2: error: `FOO' undeclared (first use this function)
foo.C:2: error: (Each undeclared identifier is reported only once for each
function it appears in.)
foo.C:2: error: expected `;'
foo.C:2: error: expected `}'

Especially the first one is annoying, as it directs me to
the end of the file (which is usually far away :-)

In non-macro context multiline strings are correctly noted as an error.
