This list does not say much and it is even obsolete, at least "mingw" supports
ftw(); although Eli disagrees in:

On MacOS X GDB does not work anyway, FreeBSD latest stable release is 10.1 so
5.2.1 seems irrelevant, NetBSD 6.1.5 vs. 3.0 likewise, for other OS I have no
idea if they are supported by GDB and nobody knows - configure.{host,tgt}
triplets naming are too cryptic to quickly check it by someone not familiar
with that platform and there is no official list of supported platforms
I asked for recently at least in:

As global maintainer Eli asked for ftw()->fts() (despite I do not see there
valid technical argument in that mail myself) going to implement it; otherwise
I would not see from the platform list at
if ftw() is really supported on all GDB hosts or not.
