Parse errors in system include files are most often the result of text/binary
mode incompatibilities.  If you check this file with a binary editor, you 
will most likely see \r\n line endings.  My guess is that the mount point 
that you have for / is binary (default in the latest net release).  If you
want to interpret files in text mode, you should mount text mode.  If
you want to keep binary mounts which will open all files (not otherwise 
specified) as binary, you need to remove the \r from files like stdio.h.
Its your choice and once you make the decision and route out all the 
incompatible files, you'll find things are pretty smooth sailing.  Of 
course, as with any half-baked idea like different formats for files in 
different "modes", you'll still find cases where you're "damed if you do
and damned if you don't."

Good luck!
