[mythtv] Errors compiling mythfrontend

[Andrew Kimpton]

I'm getting a stream of errors when building this evenings trunk from  
svn on Mac OS X. These seem new (in the last week), and I can 'avoid'  
them by inserting a #include <CoreFoundation/CoreFoundation.h> in the  
middle of the headers at the top main.cpp (specificlly between  
"manualbox.h" and "manualschedule.h". Neither of these two particular  
headers have changed recently so I'm sure it's something else, but  
I'm having a tough time figuring out what.

If someone has some suggestions - that'd be great ! The specific  
errors I'm getting are :

/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBase.h: 
195: error: 'always_inline' was not declared in this scope
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBase.h: 
195: error: expected `)' before 'inline'
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBase.h: 
195: error: expected `)' before 'inline'
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBase.h: 
195: error: expected unqualified-id before ')' token
/System/Library/Frameworks/CoreFoundation.framework/Headers/ 
CFString.h:697: error: 'always_inline' was not declared in this scope
/System/Library/Frameworks/CoreFoundation.framework/Headers/ 
CFString.h:697: error: expected `)' before 'inline'
/System/Library/Frameworks/CoreFoundation.framework/Headers/ 
CFString.h:697: error: expected `)' before 'inline'
/System/Library/Frameworks/CoreFoundation.framework/Headers/ 
CFString.h:697: error: expected unqualified-id before '

and so on for about 150 lines or so - basically it looks like the gcc  
attributes for inlining that the CFBase.h header defines are not  
being recognized by the compiler !? Is something redefining  
__attribute__ for their own purposes ? libs/libavutil/common.h has  
the following line :

#define always_inline __attribute__((always_inline)) inline

Which strikes me as being dangerous since if anyone else uses  
__attribute__ ((always_inline)) after this #define they'll get :

__attribute__ ((__attribute__((always_inline)) inline))

but that header hasn't changed in 2 months or so. Has it recently  
gotten included into the headers for mythfrontend/main.cpp ?

Thanks
