  28 Test VariantDir handling of removal of source files.
  29
  30 A C++ Program is created and compiled. First, a header is missing. Then
  31 the header is added and the compilation should succeed, then the header
  32 is removed and the compilation should fail again.
  33
  34 Previous versions of SCons did not remove the header from the build
  35 directory after the source directory's header was removed, which caused
  36 the compilation to succeed even after the source file was removed.
  37
  38 Test case supplied by Patrick Mezard--many thanks.
