-Subject: [PATCH] fix return value of wcs{,n}cmp for near-limits signed wchar_t values
-
-The standard states that:
-
-  > Unless explicitly stated otherwise, the functions described in
-    this subclause order two wide characters the same way as two
-    integers of the underlying integer type designated by `wchar_t`.
-  > [...]
-  > The `wcscmp` function returns an integer greater than, equal to,
-    or less than zero, accordingly as the wide string pointed to by s1
-    is greater than, equal to, or less than the wide string pointed to
-    by s2.
-  > The `wcsncmp` function returns an integer greater than, equal to,
-    or less than zero, accordingly as the possibly null-terminated
-    array pointed to by s1 is greater than, equal to, or less than the
-    possibly null-terminated array pointed to by s2
-  - N3047 (latest C draft as of the time of writing)
-
-Yet a simple test program such as this:
-
-    #include <wchar.h>
-    #include <stdio.h>
-
-    int main()
-    {
-        wchar_t str1[2] = { WCHAR_MAX, L'\0' };
-        wchar_t str2[2] = { WCHAR_MIN, L'\0' };
-
-        printf("%d\n", wcscmp(str1, str2));
-        printf("%d\n", wcsncmp(str1, str2, 1));
-    }
-
-Will fail to run correctly according to this specification on musl (on
-targets that have signed wchar_t), as it will print -1 instead of
-1 (it should print 1, since WCHAR_MAX > WCHAR_MIN).
-
-This appears to be due to the fact that musl uses a simple subtraction
-to implement wcscmp and wcsncmp, which may result in an overflow.
-
-This patch fixes this by replacing the subtraction with a little bit
-of code that orders the characters correctly, returning -1 if the
-character from the first string is smaller than the one from the
-second, 0 if they are equal and 1 if the character from the first
-string is larger than the one from the second
