Unfortunately this produces an absolute ton of spurious warnings which
scroll off my terminal buffer. I think I’ve caught all the important
ones now, though.
I’ve attached my latest go with this. I’ve removed the
MAC_OS_X_VERSION_10_XX macros with their numbers, as we can use the
existence of the macros to tell what platform we’re compiling on. Eg.
#if !defined (MAC_OS_X_VERSION_10_7) \
&& MAC_OS_X_VERSION_MAX_ALLOWED >= 1070
I’ve also used the NSAppKitVersionNumber macros in a few places to do
runtime version detection. I’m not sure this is reliable. There are
two methods of finding the OS version definitively, which we can use
if we need to.
I’ve got rid of the HAS_NATIVE_FS macro and tried to replace it with
other checks where required. It compiles on 10.12, but I’m not at all
convinced it will compile on 10.6.
New 10.7 variables that need to be available on 10.6 when we’re
compiling for 10.7+ have been added near the bottom of nsterm.h.
Overall it looks quite different in places, but the functionality
hasn’t really changed.
