I guess that patch needs an added -Ilib/ms option.

I agree.  Thanks.
I'm about to push this for you.

-GREP DJGPP README
-=================
-
-To compile the GNU grep package with DJGPP tools, you will need the
-following tools (the names of the archives on DJGPP ftp sites where
-these tools are available are in parentheses):
-
-          -  The basic DJGPP development environment, including the
-             GCC compiler and the libraries (v2gnu/gccNNNb.zip,
-             v2gnu/bnuNNNb.zip, v2/djdevNNN.zip).
-
-          -  GNU Make revision 3.75 or later (v2gnu/makNNNb.zip).
-
-          -  GNU Bash (v2gnu/bshNNNb.zip).
-
-          -  GNU Sed (v2gnu/sedNNNb.zip).
-
-          -  GNU M4 (v2gnu/m4-NNNb.zip).
-
-          -  GNU Fileutils (v2gnu/filNNNb.zip), Textutils
-             (v2gnu/txtNNNb.zip) and Diffutils (v2gnu/difNNNb.zip).
-
-          -  A (previous version of) GNU grep (v2gnu/grepNNb.zip).
-
-Running the tests ("make check" in the top-level directory)
-additionally requires Gawk (v2gnu/gwkNNNb.zip).  TAGS and ID targets
-require `etags' (from the Emacs distribution) and `mkid' (from
-ID-utils, v2gnu/iduNNb.zip), respectively.
-
-All of these tools are available from the DJGPP archive sites.
-
-To build grep:
-          sh autogen.sh
-      sh configure
-          make
-
-
-Source distributions on DJGPP sites usually come pre-configured, so
-all you need to do in order to build the programs is to say "make".
-However, source distributions on GNU ftp sites, like ftp.gnu.org,
-need to be configured by running sh configure.  You will also need
-to run it if you need to configure grep differently than for the
-default configuration, for example if you want to install the programs
-in a directory other than the bin subdirectory of your DJGPP
-installation.
-
-To test that the package works, say "make check".  If you don't have a
-file named sh.exe somewhere on your PATH, "make check" will refuse to
-run, as it needs a Unix-like shell.
-
-To install, either copy the executables and man pages to the
-appropriate directories, or say "make install".  To clean up, say
-"make clean" or "make distclean".
-
-Please note the -u and -U options that specifically target MS-DOS and
-MS-Windows environments.  They are described in the grep man page in
-this distribution.
-
-National Language Support doesn't work in this port, so don't expect
-the programs to talk to you in any language but English.
-
-Please post any problems in the DOS version to the comp.os.msdos.djgpp
-news group first, especially if they have something to do with the
-DOS-specific aspects.
-
-To create the files required for the documentation package
-perform the following in the docs directory:
-        make grep.dvi
-        make grep.ps
-        makeinfo --html grep.texi -o grep.html
