I find in my package configuration:

/home/jmills/depot/trapeze/ECOSBUILD/dist/install/include/pkgconf/hal.h:
 #define CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_VERSION 1

If I understand your track here, that would activate the following lines
in 'hal_if.c':

#ifdef CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_VERSION
    CYGACC_CALL_IF_MONITOR_VERSION_SET(0);
#endif

which, I suppose, would in turn cause
    CYGACC_CALL_IF_MONITOR_VERSION() to resolve as '0', or NULL.

Hence my <null> print string.

Is that sensible?
