I think the problem is using static libraries.  IIRC, on Mac OS X, if 
you link against two static libs -lA -lB, order is important, and if B 
need symbols from A (that the executable into which the two are linked 
does not already take from A), it won't find them.  What could help in 
this specific case is to switch the order of x2c_support and x2c_xcd in 
xml2cmp/Executable_*.mk.  (Will try that out on my Mac, but that can 
take a while.  Another solution might be to use Mac OS X ld switches 
-all_load or -force_load.)

In general, I think using static libraries to link individual objects 
into multiple dynamic libraries or executables will not work smoothly 
across all our platforms.  (I experimented with that earlier this year, 
thinking that it might help write CppUnit tests that can access private 
symbols of to-be-tested dynamic libraries, but only got lost in problems.)
