Thats not where I find such files on my system. All the .xclangspec  
files are in one directory
~me$ find /Developer -name \*.xclangspec
/Developer/Library/PrivateFrameworks/XcodeEdit.framework/Versions/A/ 
Resources/Ada.xclangspec
/Developer/Library/PrivateFrameworks/XcodeEdit.framework/Versions/A/ 
Resources/BaseSupport.xclangspec
/Developer/Library/PrivateFrameworks/XcodeEdit.framework/Versions/A/ 
Resources/C++.xclangspec
Snipped remaining 20 or so versions

Some of the .pbfilespec files are there althought there a acouple of  
other spots as well:

~me$ find /Developer -name \*.pbfilespec
/Developer/Applications/Dashcode.app/Contents/Frameworks/ 
CYKit.framework/Versions/A/Resources/Cayenne.pbfilespec
/Developer/Library/PrivateFrameworks/DevToolsCore.framework/Versions/A/ 
Resources/Built-in file types.pbfilespec
/Developer/Library/PrivateFrameworks/DevToolsCore.framework/Versions/A/ 
Resources/Standard file types.pbfilespec
/Developer/Library/Xcode/Plug-ins/IBCompilerPlugin.xcplugin/Contents/ 
Resources/Interface Builder File Types.pbfilespec
/Developer/Library/Xcode/Plug-ins/XdesignCompilerPlugin.xcplugin/ 
Contents/Resources/Xdesign file types.pbfilespec

When I drag those two files to that directory, Xcode does some  
highlighting but only of non-reserved words and comments, and also  
does "(" and "{" matching if you move the cursor forward over a ")" or  
"}", but not if the cursor is moved backwards.)  Also shows some code  
completion. I'm not sure what was _supposed_ to happen, but I do see  
some behavior that suggests _some_ of those efforts were having a  
desired effect.
