           Summary: merging with K&R declaration mismatch with gcc
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: daniel at zuster.org
                CC: llvmbugs at cs.uiuc.edu

clang & gcc differ in how they treat the following code:
void g0(int, int);
void g0();
//void g0(int);

void f1() {
  g0(1, 2, 3);

clang merges the declarations so that g0 is g0() after the second declaration;
and therefore allows the commented out redefinition, and the call. gcc errors
on both.
