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.
