util-linux: fix ncurses/wchar handling (again)HEADmaster
Since commit 006a328ad6bed214ec3c4d92120510ea37329dd1 ("util-linux: fix build with ncurses"), we have a build failure that occurs with musl and uClibc-ng toolchains when wide-char support is not enabled in ncurses. The problem occurs because util-linux #defines its own wchar_t (as char) when configured without widechar support. It was fixed upstream, so pull the corresponding patch from the util-linux git repository.

+Subject: [PATCH] build-sys: fix compilation with ncurses and uClibc or musl
+ libc
+
+Compiling util-linux with musl and uClibc-ng toolchains when wide-char
+support is not enabled in ncurses results in compilation failures with
+the following message:
+
+ error: two or more data types in declaration specifiers
+ #define
+ wchar_t char
+
+The problem occurs because util-linux #defines its own wchar_t (as char)
+when configured without widechar support. This conflicts with definition
+of wchar_t contained in stddef.h.
+
+This error can be reproduced running "<toolchain-cc -o test test.c" with
+the following test program:
+
+ #include <ctype.h>
+ #define wchar_t char
+ #include <stddef.h>
+
+ int main()
+ {
+ return 0;
+ }
+
+The only way to avoid the problem it to reorder the inclusion of headers
+in some files under the text-utils directory.
+
