[bug-grep] grep-2.5.1a: build comments

[Nelson H. F. Beebe]

I've just completed build attempts for grep-2.5.1a on about twenty
flavors of Unix.  Most succeeded, but there were a few problems.

(1) The config.{guess,sub} files are too old (2002-vintage), and grep
    configuration fails on GNU/Linux on MIPS.  Once I replaced them
    with copies from our mirror of the latest versions (dated
    13-Nov-2004 and 16-Nov-2004, respectively), obtained by

        wget 
http://savannah.gnu.org/cgi-bin/viewcvs/config/config/config.guess?rev=HEAD&content-type=text/plain
        wget 
http://savannah.gnu.org/cgi-bin/viewcvs/config/config/config.sub?rev=HEAD&content-type=text/plain

    the configuration, build, and validation tests were successful.

(2) Builds with native compilers failed on some systems.  By switching
    to gcc, I was able to complete the builds and pass the validation
    tests on all but one (NetBSD) of the failing systems.  However,
    the failures may indicate portability problems that should be
    addressed.

Here is a summary of the build problems and build failures; complete
logs are available on request:
