OK. Rebuilding on the head.

I am happy to do and from your description it sounds like the it would
have built
if the code had my previous patch to add CFLAGS_FOR_TARGET to the
GNATLIBCFLAGS.

GNATLIBCFLAGS_FOR_C = -W -Wall $(GNATLIBCFLAGS) $(CFLAGS_FOR_TARGET) \
        -fexceptions -DIN_RTS -DHAVE_GETIPINFO

But the build didn't get far enough to know. It fails before that with:

gcc -c -g -O2  -gnatpg -gnata -W -Wall -nostdinc -I- -I. -Iada/generated
-Iada -I/users/joel/test-gcc/gcc/gcc/ada
-I/users/joel/test-gcc/gcc/gcc/ada/gcc-interface

Any ideas?

My native compiler is from the head back in August. I will rebuild it
overnight
and try again in the morning in case that's a factor.
