Running the GUI version of emacs with the -Q flag does produce the problem. (I know that -Q was effective because I did not see the splash screen and none of the changes from my init file were visible.)
When I right-click on rcsdiff.exe and co.exe in the Windows Explorer, and select Properties there is no Program tab. I do not know for sure what version these RCS files are. I think they are pure Gnu version, back when files compiled for Windows were made available. I think they are for windows, not for DOS, e.g. see first line from strings below. Running strings on rcslib.dll produces these lines (and lots of other junk that I omitted) !This program cannot be run in DOS mode. $Id: rcssyn.c,v 5.15 1995/06/16 06:19:24 eggert Exp $ $Id: rcsgen.c,v 5.16 1995/06/16 06:19:24 eggert Exp $ $Id: rcsedit.c,v 5.19 1995/06/16 06:19:24 eggert Exp $ $Id: rcskeys.c,v 5.4 1995/06/16 06:19:24 eggert Exp $ $Id: rcsmap.c,v 5.3 1995/06/16 06:19:24 eggert Exp $ $Id: rcsrev.c,v 5.10 1995/06/16 06:19:24 eggert Exp $ $Id: rcsutil.c,v 5.20 1995/06/16 06:19:24 eggert Exp $ $Id: rcsfnms.c,v 5.16 1995/06/16 06:19:24 eggert Exp $ 5.7 Note that one output line from strings is "5.7" which I suspect s the version number. Running strings on rcsdiff produced 2 lines with eggert: $Id: rcsbase.h,v 5.20 1995/06/16 06:19:24 eggert Exp $ $Id: rcsdiff.c,v 5.19 1995/06/16 06:19:24 eggert Exp $ but nothing that matched "5\." Running strings on co.exe and rcs.exe are like that for rcsdiff.exe; 2 lines by eggert and no matches of "5\."

The same idea I already mentioned: what port of RCS are you using? Can it, by chance, be an old DOS port? What do you see if you right-click on rcsdiff.exe and co.exe in the Windows Explorer, and select Properties? -- do you see a Program tab there?
