us up to version 2.17.50.20070703, at the last GPLv2 commit. Amongst others, this added upstream support for some FreeBSD-specific things that we previously had to manually hack in, such as the OSABI label support, and so on. There are also quite a number of new files, some for cpu's (e.g. SPU) that we may or may not be interested in, but those can be cleaned up later on, if needed.

Return zero if the two file names @var{s1} and @var{s2} are equivalent.
|
|
If not equivalent, the returned value is similar to what @code{strcmp}
|
|
would return. In other words, it returns a negative value if @var{s1}
|
|
is less than @var{s2}, or a positive value if @var{s2} is greater than
|
|
@var{s2}.
|
|
|
|
This function does not normalize file names. As a result, this function
|
|
will treat filenames that are spelled differently as different even in
|
|
the case when the two filenames point to the same underlying file.
|
|
However, it does handle the fact that on DOS-like file systems, forward
|
|
and backward slashes are equal.
