Yes, bloat is added even when ENABLE_STARTUP_LOCALE isn't set.  Bloat is
added even when no ctype function is called (this is normal for most
programs in /bin and /sbin - grep shows "ctype.h" in only 25 out of 80
programs in /usr/src/[s]bin.

For me, the `hack' is the global placement of the test.  It's good
for fixing everything at once, but is wasteful.

This wouldn't reduce the bloat because lots of code is required to
pull in the default locale.

More measurements:

	size of /bin/cat with    locale support: 64K
	size of /bin/cat without locale support: 44K
	(cat uses ctype only for cat -v)
	time for 1000 fork+execs with ENABLE_STARTUP_LOCALE unset:
		 92.81 real  6.47 user 76.68 sys
	time for 1000 fork+execs with ENABLE_STARTUP_LOCALE set
		and LANG set to it_IT.ISO_8859-1:
		112.58 real 15.43 user 94.89 sys
