Time again for some djgpp patches.
I mainly made GNU make put the .o-files in a djgpp/ sub-dir.

Some of the makefile.dj files in CVS have somehow got
CR-CR-LF endings. Hence the big diffs on some files. You could
perhaps rename them to Makefile.dj.

And a fix for a potential fatal error in hostip4.c; it calls free() on
something not malloced (retval from gethostbyname).
