Hello Dmitri,

Thanks for the report.

This doesn't match my experience with Sun C/C++ 5.9 (I think it was that
version).  Libtool CVS HEAD has support for this on GNU/Linux, it uses
-KPIC as PIC flag, and `-Qoption ld ' for C++, `-Wl,' for C, and an
empty wl flag for Fortran; also it avoids matching for the compiler
name, as IIRC the suite uses multiple aliases.

It would be helpful if you could download and build a nightly snapshot
of CVS HEAD (see URL on the Libtool homepage) with your Sun compiler
suite, and send verbose testsuite output for both the old and the new
testsuite, as explained in README, for failures you encounter.
