Frank,

I am building with the built in copy

On my configuration, tif_jpeg.c uses "boolean" type from RPCNDR.H as 
"unsigned char", but jpeg/libjpeg/jmorecfg.h uses it as "int"...

Changing in jmorecfg.h

#ifndef HAVE_BOOLEAN
typedef int boolean;
#endif

to

#ifndef HAVE_BOOLEAN
typedef unsigned char boolean;
#endif

works for me.

Are you sure the actual CVS GDAL built with built in JPEG lib works well 
about JPEG-in-TIFF ? because it seems libjpeg and tif_jpeg.c are compiled 
with different sizes for booleans on Win32...
