Hi,
It was reported to me that mingw32 has no readlink() function. The xreadlink
module does not take care of this yet. Jim, in the coreutils, uses a stub
int
readlink (const char *filename, char *buffer, size_t size)
{
errno = EINVAL;
return -1;
}
in an extra file. But since the purpose of xreadlink.c is that everyone
uses only xreadlink() and not the low-level readlink(), I'd propose this
more lightweight change.
Opinions?
Bruno
