 Removing the "-O3" optimization flag avoids the internal compiler error.
 The following patch accomplishes this:

 I would prefer modifying the flags for only those sources that present

 up while compiling a different source file:

 Also, I thought -current updated GCC to 4.8.5?  My macppc and sparc systems
 running 7.99.21 report GCC 4.8.4.

 I should have mentioned that this is with pkgsrc-HEAD during the freeze
 before pkgsrc-2015Q3.

 The workaround posted before still applies in my case.

 I would guess that my usual update builds did not repopulate the
 destination directory or release sets.  The host cross-gcc is 4.8.5.
 Doing a non-update release build of macppc now.

 Will try rebuilding libvpx without my workaround when I have a native
 GCC 4.8.5.

 Seems I did have gcc 4.8.5, but the string emitted by "--version" was
 stale due to being an update build.  Following non-update build the
 internal version symbol and "--version" output agree on 4.8.5.

 So, the problem persists with gcc 4.8.5 and the workaround is still
 necessary.

 As of 17 December 2015, libvpx v1.5.0 compiles without the hack
 posted earlier in this PR.

 There still seems to be some problem as later attempting to build
 "multimedia/ffmpeg010" fails claiming insufficient libvpx version.

 This complaint stems from "ffmpeg010"'s ./configure test program
 failing to link against libvpx, complaining that there are a number
 of undefined references:

 I'll reinstate the hack, rebuild libvpx, and try again.

 As of pkgsrc-HEAD prior to the pkgsrc-2015Q4 branch (libvpx 1.5.0) on
 NetBSD/macppc-7.99.24 with GCC 4.8.5, the internal compiler error
 no-longer occurs.

 The contents of the WRKSRC directory has changed making the
 previously-posted hack irrelevant.

 While libvpx compiles and links without any special treatment, it appears
 to be broken.  Configuring other packages which depend on it--particularly
 ffmpeg010--fails with undefined references as noted previously.

 As that's a subject for a different PR, this one may be closed.

 With the removal of PowerPC support from libvpx 1.5.0, it's not clear
 whether the problem has disappeared or is just masked by my primitive
 hacks to get it to compile and link reasonably.

 If I can transplant the PowerPC support from libvpx 1.4.0 to 1.5.0,
 it may yet reappear, so don't close this PR.

 Thanks.

 I've done this (see PR pkg/50814).  The problem remains for GCC 4.x.

 GCC 5.3.0 (as of 7.99.29 or so) does not exhibit this problem.

 See also PR toolchain/50570.
