-//======================================================================
-
-// The purpose of this header file is to replicate appropriate
-// functionality from the target-side header file <pkgconf/infra.h>.
-// This header file is intended to contain configuration options
-// related to the implementation of the infrastructure, as opposed
-// to how that infrastructure gets used by other packages. A good
-// example would be a configuration option to control the size
-// of the circular trace buffer.
-//
-// On the host side these things are handled by autoconf, and in
-// particular the configure.in script will offer command-line
-// arguments allowing the relevant options to be controlled.
-// The relevant information will end up in <cyg/pkgconf/hostinfra.h>
-# include <pkgconf/hostinfra.h>
-
-// Some options should always be enabled in this header file.
-#define CYGDBG_INFRA_DIAG_PRINTF_USE_VARARG
-#define CYGDBG_INFRA_DEBUG_ASSERT_MESSAGE
-#define CYGDBG_INFRA_DEBUG_TRACE_MESSAGE
-
-// Other options should be decided on a package by package basis,
-// e.g. whether or not assertions are used. On the host side it is
-// not appropriate to control these globally, instead the infrastructure
-// always provides the necessary functionality and it is up to the
-// other parts of the system to decide whether or not the facilities
-// get used.
-
-// A third set of options deal with the environment, e.g. the sizes
-// of various data types. autoconf macros take care of most of the
-// work, but some translation is needed into eCos-style names to
-// avoid namespace pollution.
-
-// Process the definitions of SIZEOF_INT_P and SIZEOF_LONG to work
-// out a sensible data type for CYG_ADDRESS and CYG_ADDRWORD.
-
-#if (!defined(SIZEOF_INT_P) || !defined(SIZEOF_LONG))
-# error "Configure problem: data type sizes not set"
-#endif
-
-#if (SIZEOF_INT_P == 4)

-#elif (SIZEOF_INT_P == 8)

-# define cyg_haladdrword cyg_halint64

-#endif
-
-// Any symbols defined in <pkgconf/hostconf.h> which have been processed
-// here should no longer be of any interest, and in the interests of
-// reducing name space pollution they get undef'ed here.
-
-// In addition there are two #define's in the config.h header file
-// which are always present and which have names that are rather too
-// generic. These get removed here as well. The version is worth
-// preserving under a different name.
