ptlib2.60-2.60-3 build problem on 10.5.6

Xcode 3.1.2.  The issue looks like something is expecting a different
argument list than Leopard provides:

...
g++ -I/sw/src/fink.build/ptlib2.6.0-2.6.0-3/ptlib-2.6.0/include 
-Wno-long-double -DPTRACING=1 -D_REENTRANT  -I/sw/include   
-I/sw/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE   -fno-exceptions
-I/sw/include -Wall  -D__MACOSX__ -m486 -DNDEBUG -O2
-I/sw/src/fink.build/ptlib2.6.0-2.6.0-3/ptlib-2.6.0/include -fno-common
-dynamic -felide-constructors -Wreorder -I/sw/include -c
