Re: [Gnustep-cvs] r31804 - /libs/base/trunk/Headers/Foundation/NSBundle.h

[Nicola Pero]

Support for attributes of Objective-C methods was added in GCC 4.6.0  
(not released yet).  Older GCCs
do not recognize them and will throw a parse error whenever they  
encounter them. :-(

So, it's not just a matter of that specific attribute not being  
recognized (that would normally generate a warning
which you can turn off with a command-line flag); it's *all*  
attributes that don't work with GCC 4.5.0, as the parser
doesn't recognize them at all.

Thanks
