Leopard, Mac OS X 10.5, has:

/opt/mports/trunk/dports/devel/ld64/files/ld64-97-no-Availability.h.patch
/usr/include/AvailabilityMacros.h

Its AvailabilityMacros.h file seems to be equivalent to Availability.h.

[Schamschula (Marius Schamschula)]

Unfortunately, I have no way of testing this (my oldest test machine runs Leopard PPC), which has built this version of gnutls cleanly. Patches welcome.

[Schamschula (Marius Schamschula)]

Please try the above patch.

Replying to kencu:

I used a similar patch – and GnuTLS 3.5.11 built meanwhile (100 minutes).

Marius,

that patch needed one more #endif to work, but did work

$ port -v installed gnutls
The following ports are currently installed:
  gnutls @3.3.21_0 platform='darwin 8' archs='ppc' date='2016-03-01T11:45:13-0800'

  gnutls @3.5.10_0 platform='darwin 8' archs='ppc' date='2017-03-27T04:51:37-0700'
  gnutls @3.5.11_0 (active) platform='darwin 8' archs='ppc' date='2017-04-14T10:27:24-0700'

here's the revised bit

#ifdef __APPLE__
# include <CoreFoundation/CoreFoundation.h>
# include <Security/Security.h>
#ifndef __MAC_OS_X_VERSION_MIN_REQUIRED
#if __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ >= 1050
# include <Availability.h>
#else
# include <AvailabilityMacros.h>
#endif
#endif
#endif

Of note, it also works perfectly well to do this instead:

sudo ln -s /usr/include/AvailabilityMacros.h /usr/include/Availability.h

even tho that is terribly evil and to be scorned. :>

[kencu (Ken)]

here's a new patchfile with the correction, with the same name, that works.
