parse a #include'd file which does not pass S_ISREG() if the environment variable
CPP_RESTRICTED is set.
This is primarily intended for use by programs such as calendar(1) which
use cpp to parse untrusted user files -- without this change (and the corresponding
change to calendar(1)), any user can cause a denial-of-service for the daily
calendar -a run by #include'ing a named pipe.
Many thanks to christos@netbsd for his help in polishing this.
is, use the symbol versioning script to remove certain symbols from the
dynamic symbol table.
Do the symbol versioning thing for all platforms.
Whilest our ld.elf_so(1) doesn't understand symbol versioning this
doesn't matter as all the exposed symbols appear unversioned until symbol
versioning support is added (if ever).

- updates LIBGCC_SPEC to use them appropriately.
There's a hack in here at the moment with respect to libgcc_so in that it
is preferable to link against libgcc_so will only when -shared-libgcc is
specified (the c++ frontend does this automatically.) Configurations where
LINK_EH_SPEC is defined already do this. The gcc configuration for
NetBSD/alpha and another NetBSD platform (I forget which) actually define
LINK_EH_SPEC probably by accident rather than design.
- updates share/mk to use the compiler's knowledge of what needs linking into
libraries and executables. This removes an hppa hack.
- updates the sets for the newly created libgcc* files.
- support for linking against the _pg version of libgcc has been removed.
- Disable symbol versioning (for now)
- Make sure that libiberty knows its being configured with a
cross compiler.

* loop.c (update_giv_derive): Ignore redundant sets of a biv

This fixes the underlying problem in toolchain/23002.
So the problem is thus:
* The {u,}mulsidi3 generate two parallel sets which modify the upper and lower
halves of the target register.
* life_analysis() does not track subregister modifications -- if you don't
modify the whole register with a single set, it considers the register
unused.
The simple, if klugy, solution to this is to stick an explicit clobber in. It
seems to work.
While doing this, I noticed that constant folding was not happening for
32x32->64 multiplies. This is because the parallel set generated by
{u,}mulsidi3 cannot be folded at all. To solve this, I first expand to a
normal multiply, and then use a define_insn_and_split to convert it to the
parallel set after CSE and constant folding.
This patch has also been submitted to GCC bugzilla, but who knows if I'll get
a reply to that.
