As Andris mentioned, this should say std::string.  gcc3 is much more
standards-compliant than its predecessors and has the std namespace on
by default.

And I'm sure it'll help many others as well.

I'm not entirely sure this is still needed; at least I don't recall
problems with this.  Still, it probably doesn't hurt either.

This is just a workaround - you still won't get PATH_MAX by
including <limits.h>, I think.  The proper fix would be to
change gcc's version of limits.h to #include_next "limits.h"
before its final #endif (I think this is how Andris' port
does it as well, but I'm not sure).  The file in question
seems to be gcc/glimits.h (which gets installed as
$prefix/lib/gcc-lib/$target/$version/include/limits.h).
