           Summary: Enable GNU inline semantics selectively in C99 mode
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: other
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedclangbugs at nondot.org

Per David Chisnall's comments in PR 3989, some platforms have glibc headers
that expect GNU inline semantics even in C99 mode, which causes linking
problems when building with Clang. 

Implementing -fgnu89-inline works around part of the problem (and is probably a
good idea in general), but that's a big hammer: we really want only those
functions defined in the glibc headers to get GNU inline semantics.
