lynx-dev minor patch (use _WIN_CC with DJGPP)

[Leonid Pauzner]

* Tweak xsystem.c (extern system_is_NT now ifdef'ed with WIN_EX) so
  exec_command() can also be used with DJGPP when compiled with _WIN_CC symbol.



BTW,
    #define _WIN_CC=    .... for Windows C Compiler
now used for exec_command() only - a better name may be a good idea.
