Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot Mathieu
...
- '//' replaced by '/* */'
- inclusion of int.h in int.c
- inclusion of j2k.h in int.h in order to export symbols
- adding (void) var when a variable is declared but not used
- some explicit cast
- CLOCKS_PER_SEC is declared as float in bcc55, so there is a need to cast it to int for the modulo operation
- some variables changed from float -> double

* Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the command line when encoding an image generates layers with the corresponding psnr. You have to specify values in the increase order. This option is incompatible with "-r" or "-f" options.
...
* Old -q option is now available with -f
* The INDEX-file structure has been modified and is now like this :
------------------------------
image_width image_height
progression order
tile_width tile_height
nb_tiles_width nb_tiles_height
nb_components
nb_layers
nb_decompositions
