You can also build it in a separate target of the same project and  
then change the target-specific flags for that C library (as in the  
"FPC-C-C++ Carbon Application 2.2.0" template).

myapp.app is a folder (or more specifically, a bundle). The actual  
program is .../myapp/build/Release/myapp.app/Contents/MacOS/myapp

You have to go to the project's build settings for the configuration  
that you are building (presumably "release"), and then set the  
"Architectures" setting (the second from the top) to "Standard (32-bit  
Universal)". This works at least for me with the "FPC-C-C++ Carbon  
Application 2.2.0" template.
