Log message:
Reset CFLAGS/CXXFLAGS at the end and add CPPFLAGS to the list.
Fixes build on NetBSD where native unwind.h is picked up otherwise.

Log message:
Don't redefine putc and friends on NetBSD.

Log message:
PR pkg/48890 was proposed. Thanks. But this commit is slightly
different from the PR (When submitting patch to pkgsrc with
adding more patches, submitter should do cvs add
patches/patch-hoge, before creating the pkgsrc patch, thanks).

I belive both simulavr and avr-libc will be packaged fine with this.

4.7.3 to 4.8.3  -- From grepping 'avr' from NEWS file:
--------------
   On AVR, the configure option --with-avrlibc supported since GCC 4.7.2
   is turned on per default for all non-RTEMS configurations. This option
   arranges for a better integration of [3]AVR Libc with avr-gcc. For
   technical details, see [4]PR54461. To turn off the option in non-RTEMS
   configurations, use --with-avrlibc=no. If the compiler is configured
   for RTEMS, the option is always turned off.

     * Support has been added for the AVR-specific configure option
       --with-avrlibc=yes in order to arrange for better integration of
       [3]AVR-Libc. This configure option is supported in avr-gcc 4.7.2
       and newer and will only take effect in non-RTEMS configurations. If
       avr-gcc is configured for RTEMS, the option will be ignored which
       is the same as specifying --with-avrlibc=no. See [4]PR54461 for
       more technical details.

 For the changes for 4.7, see following page.

(Picking up AVR related topic from above info):
The AVR port's libgcc has been improved and its multilib
structure has been enhanced. As a result, all objects
contributing to an application must either be compiled with
GCC versions up to 4.6.x or with GCC versions 4.7.1 or
later. If the compiler is used with AVR Libc, you need a
version that supports the new layout, i.e. implements #35407.

The AVR port's -mshort-calls command-line option has been
deprecated. It will be removed in the GCC 4.8 release. See
-mrelax for a replacement.

The AVR port only references startup code that clears .bss and
the common section resp. initializes the .data and .rodata
section provided respective sections (or subsections thereof)
are not empty, see PR18145.
  Applications that put all static storage objects into
non-standard sections and / or define all static storage
objects in assembler modules, must reference __do_clear_bss
resp. __do_copy_data by hand or undefine the symbol(s) by
means of -Wl,-u,__do_clear_bss resp. -Wl,-u,__do_copy_data.

Log message:
Bump for perl-5.20.0.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Log message:
Make sure GCC's unwind.h is picked up and not a potential copy from
/usr/include.

Log message:
GCC now wants zlib - and comes with an internal copy as an alternative to
using the system/Pkgsrc zlib.  At least on Ubuntu, the internal zlib fails to
get past configuration.

Use the standard Pkgsrc (or builtin) zlib instead.

Bump PKGREVISION to reflect the minor difference in build strategy.

Log message:
Explicitly disable LTO.

Log message:
Add buildlink3.mk file.

Log message:
Bump avr-gcc from 4.4.1 to 4.5.3

(pkgsrc)
Removing:
 patches/patch-aa
   (was not to install: install-subdir at libiberty)
 patches/patch-ac
   (was not to install tree-inline.o cppdefault.o for Mac OS X,
    equivalent target does not have these files for now)
 patches/patch-gcc_toplev.h
   Upstream corrected the problem as:
   -extern inline int
   +static inline int

Adding:
 patch-gcc_config_avr_driver-avr_c
   To fix the problem like:
   error: non-void function 'avr_device_to_arch' should return a value \ 
[-Wreturn-type]
 patch-libiberty_Makefile.in
   Not install libiberty.a
   to avoid duplication (conflict) with other cross tool-chain (mef@).

(upstream)
For the changes from 4.4.1 to 4.5, see following page.
  http://gcc.gnu.org/gcc-4.5/changes.html

Log message:
Bump all packages for perl-5.18, that
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package

Like last time, where this caused no complaints.
