Last week we had a thread (which is still not finally clarified) about
problems with shared libraries, PICFLAG  and the like. The problem was
seen only by  people using srcdir as  their  builddir. I sent  a patch
which fixes it  for me, but haven't  heard anything from  the original
posters.   I don't  know if  this could  be related   to your problem,
though.

Anyway, I'll attach the  message and append  the patch literally. Tell
me, if it helps.

OK, I found out what's going on here. The problem does exist since I don't know
when ;-) It's caused by `not finding the ../../config/*pic' files when someone
is configuring and building the runtime libs in the srcdir.

And yes, it's not a problem with make distclean.

But why didn't it show up earlier? Before my PICFLAG patch had been applied
the toplevel Makefile contained and passed the proper contents for PICFLAG
and PICFLAG_FOR_TARGET macros. Because they were passed to sub-makes nobody
recognized that configuration of the target lib{iberty,io,stdc++} actually
failed to locate the ../../config/* frags.

Right now the situation is as follows:

  1. The toplevel Makefile doesn't pass down any PICFLAG macro; hence
     each Makefile in the subdirs need to insert the contents of one
     of the pic related frags as specified in the various configure.in
     scripts.

  2. When one is building in srcdir those parts in configure.in aren't
     able to locate the frags in the toplevel/config directory because
     one ../ is missing.

Until someone has a better patch, we should add this one: (and please
_do not build your stuff in srcdir_!)
