lynx-dev DOSPATH patch

[Leonid Pauzner]

It was a long problem with cp.exe and mv.exe binaries
required for DOS port of lynx. Apparently, Hiroyuki solve this problem
by adding a variant of LYCopyFile() which does fread/fwrite in a loop -
perhaps not a good solution for UNIX (permissions...) and VMS (versions?...)
but no problem on DOSPATH systems.


* LYCopyFile(): Thanks to Hiroyuki Senshu, DOS-based systems needs no cp.exe
  binary when compiled with SH_EX.  This code now defined with DOSPATH so used
  automatically by any dos/windows port, but unused for UNIXes (permissions?)
  if occasionally built with SH_EX symbol.
* few includes labelled with _WIN_CC now tweaked with WIN_EX as should be.
