RE: depcomp problem [Fwd: Trying to compile latest CVS on old SC Ounixware 2]

[Cameron, Steve]

Ok, this compile script will compile some things.
I haven't seen it link anything, because I can't get that 
far.

Now, it seems configure decides that I don't have dirent.h, (I think)
and diff/dir.c, line 64, "DIR" comes up unknown:

I do have /usr/include/dirent.h which has a struct dirent
typedefed to be DIR, though.  There's also a /usr/include/sys/dirent.h
which looks kernel/filesystem related... maybe it's finding that and
not liking it?  (But it's always been there before too.)

Ugh.  Hard to decipher what "configure" is doing....

(And now the cvs repository seems to refuse anonymous access...
hopefully a temporary situation.)
