I'm trying to clean sources of POV-Ray from warnings outputed with gcc
3.1 under DJGPP. I have easy removed most of them but found two I
don't know how to fix.

1. "aggregate has a partly bracketed initializer"

  I know what this message mean but I don't know why this is reported
  for below definition:

  // from file_pov.h

  enum
  {
    POV_File_Unknown = 0,
    POV_File_Image_Targa = 1,
    POV_File_Image_PNG = 2,
    POV_File_Image_PPM = 3,
    POV_File_Image_PGM = 4,
    POV_File_Image_GIF = 5,
    POV_File_Image_IFF = 6,
    POV_File_Image_JPEG = 7,
    POV_File_Image_TIFF = 8,
    POV_File_Image_System = 9,
    POV_File_Text_POV = 10,
    POV_File_Text_INC = 11,
    POV_File_Text_Macro = POV_File_Text_INC, 
    POV_File_Text_INI = 12,
    POV_File_Text_CSV = 13,
    POV_File_Text_Stream = 14,
    POV_File_Text_User = 15,
    POV_File_Data_DF3 = 16,
    POV_File_Data_RCA = 17,
    POV_File_Data_LOG = 18,
    POV_File_Font_TTF = 19,
    POV_File_Unknown_Count = 20
  };

  // from file_pov.cpp

  typedef struct
  {
    char *ext[4];
  } POV_File_Extensions;

  POV_File_Extensions gPOV_File_Extensions[POV_File_Unknown_Count] =
  {
    { "",      "",      "",      ""      }, // POV_File_Unknown
    { ".tga",  ".TGA",  "",      ""      }, // POV_File_Image_Targa
    { ".png",  ".PNG",  "",      ""      }, // POV_File_Image_PNG
    { ".ppm",  ".PPM",  "",      ""      }, // POV_File_Image_PPM
    { ".pgm",  ".PGM",  "",      ""      }, // POV_File_Image_PGM
    { ".gif",  ".GIF",  "",      ""      }, // POV_File_Image_GIF
    { ".iff",  ".IFF",  "",      ""      }, // POV_File_Image_IFF
    { ".jpg",  ".JPG",  ".jpeg", ".JPEG" }, // POV_File_Image_JPEG
    { ".tif",  ".TIF",  ".tiff", ".TIFF" }, // POV_File_Image_TIFF
    { POV_IS1, POV_IS2, POV_IS3, POV_IS4 }, // POV_File_Image_System
    { ".pov",  ".POV",  "",      ""      }, // POV_File_Text_POV
    { ".inc",  ".INC",  "",      ""      }, // POV_File_Text_INC
    { ".ini",  ".INI",  "",      ""      }, // POV_File_Text_INI
    { ".csv",  ".CSV",  "",      ""      }, // POV_File_Text_CSV
    { ".txt",  ".TXT",  "",      ""      }, // POV_File_Text_Stream
    { "",      "",      "",      ""      }, // POV_File_Text_User
    { ".df3",  ".DF3",  "",      ""      }, // POV_File_Data_DF3
    { ".rca",  ".RCA",  "",      ""      }, // POV_File_Data_RCA
    { ".log",  ".LOG",  "",      ""      }, // POV_File_Data_LOG
    { ".ttf",  ".TTF",  "",      ""      }  // POV_File_Font_TTF
  };

  if you are not sure about my quoting you can check povray sources at
  http://www.povray.org/download/

2. "multi-character character constant"

Is there any way to remove this warning (of course except command line
option) for definition:

  enum
  {
      kPOVMSObjectClassID      = 'OCLA',
      kPOVMSMessageClassID     = 'MCLA',
      kPOVMSMessageIdentID     = 'MIDE',
      kPOVMSTargetAddressID    = 'MTRG',
      kPOVMSSourceAddressID    = 'MSRC',
      kPOVMSMessageTimeoutID   = 'TOUT',
      kPOVMSMessageErrorID     = 'MERR'
  };

I have additional question. I can't write warnings of compiler with
gcc under djgpp to file with simple redirection
  gcc ... > file.txt
It creates file.txt but warnings are outputted to the screen. Is it
general rule for gcc or just problem of djgpp port ? Is there switch
in options like for POV ? I can't find anything like this in
documentation. I use Win95 OSR2.
