           Summary: HAVE_DLFCN_H does not imply Dl_info
           Product: Build scripts
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: cmake
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: dje.gcc at gmail.com
                CC: llvmbugs at cs.uiuc.edu


Various files in lib/System/Unix, such as Path.inc and Signals.inc guard use of
Dl_info with HAVE_DLFCN_H but the existence of the header file does not imply
Dl_info and the support functions that use it are provided.

Similarly lib/System/Unix/DynamicLibrary.cpp includes dlfcn.h without using the
guard macro.
