I get a different set of undefined symbols.  Perhaps the first undefined 
symbol was just hiding these (although I thought ld would complain about 
ALL the undefined symbols).

MacOSX:~/gcc/obj-3.3.4+gm2-20041222/gcc ed$ gcc   -g -DIN_GCC   -W -Wall 
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes    
-DHAVE_CONFIG_H  -o stage1/gm2/gm2l               
gm2/gm2-compiler-boot/gm2l_init.o               
gm2/gm2-compiler-boot/m2flex.o               
gm2/gm2-compiler-boot/gm2l.o gm2/gm2-compiler-boot/gm2.a  
gm2/gm2-libs-boot/libgm2.a gm2/p2c/p2c-src/src/libp2c.a  
./intl/libintl.a  -liconv  ../libiberty/libiberty.a  
gm2/gm2-compiler-boot/M2Reserved.o
ld: Undefined symbols:
_SymbolKey_GetSymKey
_SymbolKey_InitTree
_SymbolKey_PutSymKey

Then I tried to do this:
MacOSX:~/gcc/obj-3.3.4+gm2-20041222/gcc ed$ gcc   -g -DIN_GCC   -W -Wall 
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes    
-DHAVE_CONFIG_H  -o stage1/gm2/gm2l               
gm2/gm2-compiler-boot/gm2l_init.o               
gm2/gm2-compiler-boot/m2flex.o               
gm2/gm2-compiler-boot/gm2l.o gm2/gm2-compiler-boot/gm2.a  
gm2/gm2-libs-boot/libgm2.a gm2/p2c/p2c-src/src/libp2c.a  
./intl/libintl.a  -liconv  ../libiberty/libiberty.a  
gm2/gm2-compiler-boot/*.o

and this compile worked (with a bunch of warnings about multiply defined 
symbols.
