I have not seen that problem. Obviously your build system differs.

You might try the statement "#undef greg_t" just before the typedef for greg_t 
in src/VBox/ExtPacks/VBoxDTrace/include/VBoxDTraceTypes.h.

Interesting that the file contains the statement
"#  include <sys/ucontext.h> /* avoid greg_t trouble */". It seems that it is 
not working.
