Ticket History #1364: make depend requires use of Gnu sed under Irix

Very low priority...

Trying to update dependencies failed to strip the the gcc include path
on an irix machine. Tracked it down to the Irix version of sed
misbehaving and not outputting the gcc relevant lines....

Perhaps - do not allow updating of dependencies unless gnu's sed is
found... I have not evaluated which versions of sed are broken...

The problem is in depgen.sed. The output script is missing all of the
gcc stuff...

Here is the .depfix2.sed file with the irix sed...

s; \.\./\.\./\.\./src/lib/krb4/\.\./\.\./; $(SRCTOP)/;g
s; \.\./\.\./\.\./src/lib/krb4/\.\./\.\./; $(SRCTOP)/;g
s; \.\./\.\./\.\./src/lib/\.\./; $(SRCTOP)/;g
s; \.\./\.\./\.\./src/; $(SRCTOP)/;g

# Now try to produce pathnames relative to $(srcdir).
s; $(SRCTOP)/lib/krb4/; $(srcdir)/;g
s; $(SRCTOP)/lib/; $(srcdir)/../;g

# Now substitute for BUILDTOP:
s; \.\./\.\./; $(BUILDTOP)/;g

# end of sed code generated by depgen.sed

If I use gnu sed - the top of the file is....

Actually, it seems to be the "s///p" form (print *if* a substitution was
done) that IRIX sed is treating differently, and only when it's followed
by more modifications to the pattern space, printing, etc. I believe
the substitutions are arranged to always be performed, so using a
separate print command seems to be a reasonable change, and it gets me
the same results using IRIX and GNU sed.
