   No, that's definitely not it.  Cygwin emulates a Unix-like system   
   on top of Windows.  It creates executables with a ".exe" suffix,   
   but plays some tricks so that "foo.exe" also looks like "foo".   
   Also, Cygwin uses "/" as a directory separator.  When I modified   
   the caller program to set argv[0], it worked correctly.   
      
   I've updated the caller to show the result of execve() (which   
   normally doesn't return).  It returns -1 to indicate an error and   
   sets errno to 7 (E2BIG, Argument list too long) -- which is a bit   
   odd, but there's no E2SMALL code.
