Speaking of gettext, shouldn't lib/xbinary-io.c test on ENABLE_NLS
too? Because now I get:
  xbinary-io.c(34): warning C4047: 'function': 'const char *' differs in levels 
of indirection from 'int'
  xbinary-io.c(34): warning C4024: 'error': different types for formal and 
actual parameter 3

Where is '_(x)' defined if ENABLE_NLS is not defined?
