    Description

      When using the CompilationDatabaseProjectManager plugin and opening a project from a compile_commands.json file, none of the C source files in it are recognized as part of the project if the first one of them contains an "-std=" option in "arguments". Example: 

      [
          {
              "arguments": [
                  "gcc",
                  "-c",
                  "-std=gnu99",
                  "-o",
                  "obj/test.o",
                  "src/test.c"
              ],
              "directory": "/home/realnc/projects/CompDatabaseTest",
              "file": "src/test.c"
          }
      ]
      

      It doesn't matter if I replace "gcc" with g+, clang or clang+. If it's a *.c file, the "-std" argument prevents Creator from being able to parse any of the C files correctly and a yellow icon appears at the top that says: "This file is not part of any project."

      The problem doesn't exist with C++ sources. For example, this works fine: 

      [
          {
              "arguments": [
                  "g++",
                  "-c",
                  "-std=c++14",
                  "-o",
                  "obj/test.o",
                  "src/test.cpp"
              ],
              "directory": "/home/realnc/projects/CompDatabaseTest",
              "file": "src/test.cpp"
          }
      ]
