look at the first lines of my jconfig.h:

#define HAVE_BOOLEAN     // this will avoid redefinition of boolean
// the following line is probably or definitely a hack
// since it implicitly duplifies the definiction from rpcnrd.h
typedef unsigned char boolean;  //conflict with RPCNRD.H  ---

You are right, this is a known bug. Most of the IJG library features
work well without UPSAMPLE_MERGING_SUPPORTED.
