For reasons unknown that doesn't work here.  At all.

I did try to change the first line of configure script to use bash and
not just /bin/sh and that seemed to make no difference. I think there is
another email here somewhere from you mentioning egrep. Well I have GNU
grep and GNU egrep in my path at /usr/local/bin *first* before the good
old /usr/xpg4/bin/grep.  No idea why it doesn't fly here. Nope. No clue
at all. Like I said.  Baffled.  I did look to the east and I did go and
try to get a black cat but alas it was not a full moon last night. I can
tell you that configure ( once I removed those offending lines checking
for grep which I have in multiple flavours ) would report this neatly :

alpha$ ./configure --prefix=/opt/bw --disable-silent-rules \

The env var for CC is a bit of a hack but I tried that first just to see
if I could get this process off the ground.  Of course I can, the code
is good code but the configure process is a total mystery looking for
grep which I have all over the place in various flavours.  Regardless I
have to intervene and do manual linkage with libsigsegv a few times and
of course the final link for grep itself needs this. The configure
script finds libsegsegv.so of course :

checking for libsigsegv... yes
checking how to link with libsigsegv... /opt/bw/lib/libsigsegv.so -lc
-R/opt/bw/lib

However the Makefile seems to just ignore that fact. In a few places.

Again, no idea why. Baffled.

So with a little help the whole lot does compile up neatly and then the
whole testsuite runs fine except for that gnulib nit which we can
ignore.  I did repeat the whole process from top to bottom a few times
and I did use C99 with strict CFLAGS and again I do need to remove the
offensive lines looking for grep. Even though I had previously installed
grep 3.5 in the very first component of my PATH!  That was hilarious. So
the whole show compiles up neatly after this :

When I say "neatly" here I mean to say that the final link fails in that
libsigsegv was forgotten. Again, baffled about that. Manual intervention
solves the problem and I need to do that once in the test suite.

However, all in all, a damn fine looking grep.
