Re: support for SunPRO C/C++ on Linux

[Bruno Haible]

Hello Ralf,

Here is a revised patch. I changed the recognition of the Sun compilers,
and the whole_archive_flag_spec and postdeps, so that now all 112 tests PASS.

Good question. I had many SKIPs, but this was either because I had forgotten
to copy a recent config.guess, or because I did
      ./configure
      make
      make check
- not knowing that after modifying libtool.m4, a simple "make" does not
update the aclocal.m4 and configure files in the subdirectories; now I do
      ./configure
      make
      make dist
      make check
and it works much better!
