Apparently your hack does not kill #define USE_WIDE_UPPER_LOWER.
BTW, the current code for upper/lower etc. seems to be broken. The
exact problem you have are happening in Japanese encodings too(EUC_JP)
too. PostgreSQL should not use wide-character method if LC_CTYPE is C.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@xxxxxxxxxxxxxx)
