[Boost-users] [GIL] Compilation times

Hello. I'm using g++-4.4 with boost libraries and they're great. However, I have to use some image manipulation algorithms for two types of images (rgb8 and gray). I'm using it successfully, however, compilation times have increased a lot: I use apply_operation and any_image and any_image_view with two types each (rgb8 and gray8) Is there a way to decrease compile times? Thanks in advance.
