According to the documentation it is in the process of being made
part of the C++ standard:

   A proposal, N1975, to include Boost.Filesystem in Technical
   Report 2 has been accepted by the C++ Standards Committee.
   The Boost.Filesystem library will stay in alignment with the
   TR2 Filesystem proposal as it works its way through the TR2
   process.

I guess that, due to the C background of C++ (C doesn't have
a portable interface for directory and file managment) it was
not considered to be necessary for C++ to have one. And then
this is a non-trivial problem and probably there wasn't a re-
ference implementation that really worked like Boost.Flile-
system seems to do and, as far as my understanding of the
standarduzation prozess goes, getting something into the
standard without a reasonable reference implementation normally
doesn't happen. And even with a reference implementation it's
still a long process...
