Hello Everyone,
I have ten patches which are approved or obvious but waiting on commit,
each of which is attached to this email. Feel free to consider this a
ping, HOWEVER, they are rebased onto the latest trunk so they're no
longer stale. Additionally, I updated the commit messages and with
complete proposed changelog entries. They all (inside the patch file)
have a link to their approval message and the original proposal message.
Note that ANY patch that touches fixincludes has a dependency on the
first patch (0001...), as fixincludes WILL NOT RUN without this patch on
a vxworks platform.
Sorry for the long latency period but I did not have access to a
computer for a substantial period of time over the summer. I've just
been able to get everything back up and running.

Subject: [PATCH 01/10] Add ability to skip the machine_name fixincludes fix.
On some platforms, machine_name is overzealous, or even breaks things.
This patch adds the functionality to skip the machine_name 'fix' by
giving it an empty macro list.
It also removes vxworks from the list of no-op fix platforms so that
fixincludes will run on that platform (it needs it).

Subject: [PATCH 02/10] Added assert fixinclude hack for VxWorks.
VxWorks's assert.h relies on adjacent string tokens being joined,
and uses macros for some of the strings (e.g. __FILE__). However,
it does not put a space after the end quote and before the macro,
so instead of replacing the macro, gcc >= 4.7.x thinks it's a
user-defined literal token, and since the lookup obviously fails,
compilation of libstdc++ dies.
This patch just replaces the assert.h header with another one that
will work. It preserves the same format, just changes the spacing.

Subject: [PATCH 03/10] Add hack for ioctl() on VxWorks.
ioctl() is supposed to be variadic, but VxWorks only has a three
argument version with the third argument of type int. This messes
up when the third argument is not implicitly convertible to int.
This adds a macro which wraps around ioctl() and explicitly casts
the third argument to an int. This way, the most common use case
of ioctl (with a const char * for the third argument) will compile
in C++, where pointers must be explicitly casted to int.

Subject: [PATCH 06/10] Add stdint.h wrapper for VxWorks.
Vxworks stdint.h doesn't have all the typedefs needed for standards
compliance, so add a hack that adds all of the needed typedefs to be
fully compliant to the standard. Fixes broken libstdc++.
There was additional discussion of adding the necessary macros to get
gcc to have built-in recognition of the types, but I could not get that
to work. That is also non-essential to this patch, which is primarily
to fix a bug caused by relying on types in stdint.h that vxworks does
not define.

Subject: [PATCH 08/10] Add fix to make write() const correct on VxWorks
VxWorks' write() takes its second argument as non-const, so the
compiler complains if one tries to pass a const pointer to it.
This simply changes the prototype to say it is const so everything
works. I believe that the prototype is non-const for backwards
compatibility with old verisons of vxworks, but these versions are
not supported by modern GCC, so causing potential bugs on those
platforms is a non-issue. Modern vxworks will not modify the string
passed to it, so just changing the prototype will work silently.

Subject: [PATCH 09/10] Added --enable-libstdc++-v3 option.
This patch allows the user to force enable/disable building of
libstdc++-v3 with a --enable-libstdc++-v3 option to be congruent
with the other runtime library options.
The side effect of this, and the main motivation for this patch, is
to allow the user to force compilation of libstdc++-v3 for targets
that do not currently enable building libstdc++-v3 by default. The
configure-time override is useful when trying to override the stock
runtime library on embedded systems that have their own C++ library.
Please note that although this is a patch that pertains to libstdc++-v3,
it is a patch over top-level configure, NOT libstdc++-v3/configure.

Subject: [PATCH 10/10] Make open() call more compatible in gcc/gcov-io.c
In gcc/gcov-io.c, the call to open() only has two arguments. This
is fine, as long as the system open() is standards compliant.
However, on at least one system (vxworks real time processes),
open() is a non-variadic function, so the call fails. This adds
a third argument passed unconditionally to open for compatibility
with non-variadic open(). On systems with variadic open(), the
extra argument should just be ignored anyway.
When combined with one other patch this patch resolves 53264
