MacOSX: I'm having several build problems with gnupgp-2.0.16 + SVN.

[SciFi]

Hi,

I've been having several build problems on my MacOSX 10.5.8,
which is an iMac C2D, i386-apple-darwin9.8.0.
I tried 'stable' gnupg-2.0.16,
then got the SVN versions (and prereqs there),
giving me the same grief.  ;)

With the SVN version,
I first saw this problem:

And fixed it with this quicky patch:

i.e. Darwin might seem to have the same bug on this as riscos,
so I just eliminated that part of the test altogether.  ;)

I just happened to spot this similar coding trick
in ./g10/options.sh,
so I went with a similar patch here:

…

Now I am stuck with a similar yet more obstinate problem.
I can't figure out what to do with the big struct called 'opt'
as it is defined in the header ./sm/gpgsm.h:

Both modules do call for the same ./sm/gpgsm.h,
which defines the struct 'opt' starting at line 52 thru 143.
I don't remember if C can have a "extern struct …" type modifier,
else I could whip up a similar patch as above.
But which module would be the NON-extern definer?

Thanks for any help at all.
