Unfortunately, that's not going to help -- XCode uses its own build  
system, bypassing SConstruct.

I'm not sure about 2.5, but 3.0 has:

bbyer:lscript_compile bbyer$ lex --version
flex 2.5.33
bbyer:lscript_compile bbyer$ yacc --version
bison (GNU Bison) 2.3

Xcode seems to be automatically executing the following line when it  
encounters a .y file:

bbyer:lscript_compile bbyer$ yacc -o indra.y.cpp -d indra.y
conflicts: 88 reduce/reduce
bbyer:lscript_compile bbyer$ ls -l indra.y*
-rw-r--r--  1 bbyer  wheel   45812 Sep 20 12:33 indra.y
-rw-r--r--  1 bbyer  wheel  146221 Oct  1 12:31 indra.y.cpp
-rw-r--r--  1 bbyer  wheel    6131 Oct  1 12:31 indra.y.hpp

This is, presumably, because:

        -d
               Write an extra output file containing macro definitions  
for the token type names defined in
		the grammar and the semantic value typeYYSTYPE, as well as a few  
extern variable declarations.

               If the parser output file is named name.c then this  
file is named name.h.


      -o outfile
        --output-file=outfile
               Specify the name outfile for the parser file.

               The other output files' names are constructed from  
outfile as described under the -v and -d switches.


... so I guess that that's how -d responds when you tell it you want  
a .cpp file.

Do we want to fix this in the source code (by adding a third term to  
the #ifdef), or as a custom build step in the .xcodeproj?

building with late versions of XCode.
