[ANNOUNCE] Glasgow Haskell Compiler 8.0.1, release candidate 1

I've build two builds for Solaris 11.2:
Both binary distributions support shared libraries and use system
provided GMP library. If you do not have it installed then you should do
that using "pkg install library/gmp" command.
and one build for OpenBSD 5.9 (current):
This binary distribution also supports shared libraries and by default
also OpenBSD position independent executables (PIE). It requires gmp,
libffi and libiconv to be installed by "pkg_add <package>" command.
SPARC build for Solaris 11.2 is ongoing.
