Re: [PATCH 1/2] Prevent zconf.gperf from throwing an error on OSX

[Jason T. Masker]

Updated zconf.gperf patch to be conditional.

The problem is when compiling with clang/LLVM, so not necessarily
specific to OS X. Offsetof is part of C99 and defined in stddef.h, but
is builtin with gcc. This code will check for a definition and try
including stddef.h if it is not found. As a last resort, offsetof will
be defined.

I 100% agree with this patch! A newer version of gperf does make the
issue go away, it is however a good goal to not have to install
homebrew to install a newer version of gperf (I've complained about
this in the past), so...

You also need to put your sign-off here, for Yann to accept the patch.

[PATCH 0/2] OSX: Patches to make ct-ng compile & build on OSX 10.10

[Delta Tatham]

From: Daniel Zauner <delta.tatham@me.com>

An initial set of patches to ensure ct-ng compiles itself and builds cross compilers on OSX.
While I kept the patches in ./patches/ platform-agnostic, someone might need to have a look at zconf.gperf

Can we ifdef on Darwin/BSD here? If it works on other platforms, then
only the ones mentioned need stddef.h included here.

Was it a failing issue on ubuntu or debian? Did it add a warning? I'm
not around my computer, or I'd just test it myself.

The computer I'm using was built recently so not all the packages were 
there when I first tested, I know it fails the first time, but cannot 
recreate the problem now tested again on trusty and works without this 
patch.  I had installed many packages since I first tested that it may 
have fixed the original problem.

However it still fails on Mac OS X with:
