From 2832114532d92bdd533f84fa520050c5de95c012 Mon Sep 17 00:00:00 2001 From: Ramsay Jones Date: Sat, 3 Mar 2007 18:28:57 +0000 Subject: [PATCH] Fix some "comparison is always true/false" warnings. On Cygwin the wchar_t type is an unsigned short (16-bit) int. This results in the above warnings from the return statement in the wcwidth() function (in particular, the expressions involving constants with values larger than 0xffff). Simply replace the use of wchar_t with an unsigned int, typedef-ed as ucs_char_t.
