Comment (by buck):
Apple says they don't care about GNU-gcc bugs. Is there a good reason to
use gnu-gcc for all of this?

This is related to the fact that clang supports "enumeration attributes"
but GNU gcc does not.
http://clang.llvm.org/docs/LanguageExtensions.html#attributes-on-
enumerators
https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html#Attribute-Syntax
I've opened a public question on the matter at:

Summary:
Under GNU gcc, there's a syntax error in ApplicationServices.h if
$MACOSX_DEPLOYMENT_TARGET has any value less than 10.10.
Steps to Reproduce:
```
$ echo '#include <ApplicationServices/ApplicationServices.h>' |
MACOSX_DEPLOYMENT_TARGET=10.10 gcc -c -xc -
(it works, no output)
$ echo '#include <ApplicationServices/ApplicationServices.h>' |
MACOSX_DEPLOYMENT_TARGET=10.9 gcc -c -xc -
In file included from /usr/include/Availability.h:153:0,
from
/System/Library/Frameworks/ApplicationServices.framework/Headers/ApplicationServices.h:19,
from <stdin>:1:
/System/Library/Frameworks/CoreServices.framework/Frameworks/FSEvents.framework/Headers/FSEvents.h:486:41:
error: expected ',' or '}' before '__attribute__'
kFSEventStreamEventFlagItemIsHardlink
__OSX_AVAILABLE_STARTING(__MAC_10_10, __IPHONE_9_0) = 0x00100000,
^
```
