The easiest is to do a

sudo make install FPC=`pwd`/compiler/i386`

from the FPC directory after you've compiled a new FPC 2.3.1 version.  
You can always re-execute the /Developer/FreePascalCompiler/ 
iPhoneSnapshot-2.3.1-r12531/InstallScript/ 
finish_fpc_iphone_install.command script should you wish to reinstall  
the original compiler/units from the SDK.

The only side-effect of doing a "make install" is that the /usr/local/ 
bin/fpc binary will then default to FPC 2.3.1 instead of to your  
currently installed "stable" release (/usr/local/bin/ppc386 will not  
be changed though). If you want to prevent that, you can do this  
before the "make install":

cp /usr/local/bin/fpc .

and this after:

sudo mv fpc /usr/local/bin

Yes.

It's not Xcode-specific, but shell scripting. My scripts are not  
easily adaptable to a non-installed FPC, because then the layout of  
the unit directories is completely different (and I have to archive  
all object files belonging to the units in a static library for  
linking purposes, so it's not enough that the compiler can find the  
units).
