There are allot of changes between grep 2.4 and the grep 2.5. It looks like
a major upgrade, but I may be wrong.

I downloaded the CVS version last week and updated it again today. I have
produced a change zip file which can be downloaded via the URL
http://clio.rice.edu/djgpp/win2k/DJGPP_GREP25F_CHANGES.ZIP . It contains the
diff files and the updated files. At the end of this email is a short
sumamry of the changes I did to port grep 2.5f.

The only "problem" that I do not know how to resolve correctly is as
outlined in the partial email I have included below with regards to
S_ISSOCK. I have #ifdef the S_ISSOCK out in order to get it built. Can
someone please help in resolving this as I don't have time to do this this
year. Any help would be greatfully appreciated.

In the mean time could people please have a look at the grep 2.5 files
available at http://clio.rice.edu/djgpp/win2k/main.htm and let me know if I
should send the changes to the grep maintainer as they currently stand. At
least this way Grep 2.5 will build out of the box.

None of the above, IMHO.  S_ISSOCK is not sufficiently portable (even
though the latest draft of Posix requires it) for programs to use it
freely.  I think Grep should only use S_ISSOCK if it is defined, not
only for DJGPP.


------ DJGPP CHANGES -----------

The following are the changes made to Grep 2.5f in order for it to build out
of the box for DJGPP.

DJGPP cleanup:-
---------------
DJGPP 2.03 is able to use the configure scripts as it is.
1) delete DJGPP directory
2) delete patches.ac
3) delete patches.am
4) New readme.dos in main directory

The following files were modified in order for Grep to build on DJGPP :-
    configure.in            - remove DJGPP\makefile
    src\grep.c              - DJGPP does not support S_ISSOCK

The following file was modified to add change list as detailed above.
    changelog
