Hi,

My normal hack to resolve this problem is to change the following code
in tif_jpeg.c:

/* Define "boolean" as unsigned char, not int, per Windows custom. */
#if defined(WIN32)
# ifndef __RPCNDR_H__            /* don't conflict if rpcndr.h already read */
   typedef unsigned char boolean;
# endif
# define HAVE_BOOLEAN            /* prevent jmorecfg.h from redefining it */
#endif

To this:

/* Define "boolean" as unsigned char, not int, per Windows custom. */
#define boolean int
#define HAVE_BOOLEAN


The core of the problem is that some include files define boolean
differently, but it is very important to have a consistent size for it 
in the jpeg structure regardless of whether you are in the tiff code
or libjpeg itself. 

Hopefully one of the future changes to libjpeg will be to get rid of
use of this generic boolean type in favor of something unlikely
to suffer from conflicts. 

Best regards,
