Hello Dmitri,

Please keep the mailing list in Cc: so this information is conserved,
thanks.

Thanks.  I quote below the interesting part of the log.
The line containing RUNPATH gives a clue.  Please post (from the build
tree) the output of
  ./libtool --tag=CXX --config
  cat tests/testsuite.dir/29/subdir/subdemo

Are you using Gentoo?  Alternatively, which ld is used by sunCC, and why
does it have different hardcoding characteristics as suncc?  The former
seems to set only DT_RPATH, while the latter also sets DT_RUNPATH.
(I think `sunCC -v' should cause verbose output; otherwise, try `-#').
Let's see
  cd tests/testsuite.dir/29
  /bin/sh ./libtool --tag=CXX --mode=link sunCC -v -g -o subdir/subdemo 
subdir/main.o subdir/libsub.la -ldl

Libtool currently assumes that the different compilers (C, C++, Fortran)
it was configured for have the same behavior wrt. the setting of
shlibpath_overrides_runpath.  It seems that is not the case for you.
I wonder whether we need to make this a per-tag variable.  :-/

Thanks,
Ralf
