On the build settings for a target, there is a checkbox for " Use native
precompilation".


In a default new project, this box has a horizontal mark meaning it is on in
some cases and off in others, but this mark is the same (horizontal) in all
styles (Development, Deployment, Default).


Is this broken... If not how does it work exactly? Other items (Zero Link
for example) work as expected... It is horizontal for all but either checked
or unchecked in individual build configurations.


Thanks for any insight.

The dashed box can mean three things:

- mixed values when "All Configurations" are shown;
- value defined in terms of another build setting, such as in an .xcconfig file;
- value is undefined.


In the case of GCC_USE_GCC3_PFE_SUPPORT, that value is primarily for older projects originally using gcc 3.1 and is undefined in new projects, hence the dash. It will default to "yes" if undefined when you actually use gcc 3.3, and is ignored for gcc 4.x.
