Nothing.  The point is that such a space will either produce the above
error message, in which case C:\DJGPP\BIN won't be on the PATH (but we
saw it was there), or be ignored if the user uses the better
alternative for this command:

	    PATH C:\DJGPP\BIN;%PATH%

(i.e., without the `set' part and without the equals sign).

The construct %PATH% is expanded to the previous value of PATH when
the shell executes the "set PATH=" command.
