Thanks, I installed this into the Emacs trunk. I was leery about using 'mv' as the first step, because what if 'make' is interrupted right after the 'mv'? gl-comp.m4 will be missing and a later 'make' will fail because aclocal.m4 can't be built. So I instead used 'cp', as follows. === modified file 'ChangeLog' --- ChangeLog 2011-01-27 07:24:57 +0000 +++ ChangeLog 2011-01-28 00:25:24 +0000 @@ -1,3 +1,12 @@ +2011-01-28 Paul Eggert <egg...@cs.ucla.edu> + + improve fix for MS-DOS file name clash + * Makefile.in (DOS_gnulib_comp.m4): Renamed from DOS-gnulib-comp.m4, + for portability to POSIX make.
