Confirmed:

Before today, with the tables uninstalled I saw this, with subsequent test 
failures during 'make check':

checking for a traditional japanese locale... (cached) ja_JP.eucJP
checking whether mbrtowc has a correct return value... no


With today's patch to cygwin [1], and the tables uninstalled, I see this, with 
previous failures now treated as skip during 'make check':

checking for a traditional japanese locale... (cached) none
checking whether mbrtowc has a correct return value... guessing yes


And with the tables installed (with or without today's cygwin patch), I see 
this, with new 'pass' during 'make check:

checking for a traditional japanese locale... (cached) ja_JP.eucJP
checking whether mbrtowc has a correct return value... yes
