I just tried a C and Ada-only bootstrap on Mac OS X 10.3.6 (starting from
gcc 3.3, i.e.
gcc version 3.3 20030304 (Apple Computer, Inc. build 1666)
gcc version 3.3 20040312 (GNAT build 1650)
) for the first time. Linking gnatmake fails like this:
../../xgcc -B../../ -DIN_GCC `echo -O2 -g -O2 -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -fno-common |sed -e 's/-pedantic//g'
-e 's/-Wtraditional//g'` -o ../../gnatmake b_gnatm.o a-except.o ctrl_c.o

This happens because __Unwind_fallback_frame_state_for is referenced in
libgcc_eh.a and defined in libgcc.a, but gnatmake is linked with
../../collect2 -dynamic -arch ppc -weak_reference_mismatches non-weak -o
../../gnatmake -lcrt1.o ../../crt2.o -L../.. b_gnatm.o a-except.o ctrl_c.o

So there's no instance of libgcc.a to satisfy the reference from
libgcc_eh.a. Adding -lgcc_eh to the link line allows the link to complete.
