Recent gcc regression on Solaris

[Tom Tromey]

My Solaris native build now fails, where it succeeded just days ago:

./xgcc -B./ -B/ferrule/work3/tromey/java/install/sparc-sun-solaris2.6/bin/ -isystem /ferrule/work3/tromey/java/install/sparc-sun-solaris2.6/include  -DIN_GCC  -DSVR4  -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include  -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include  -g0 \

I suspect the recent defaults.h change by Kaveh Ghazi, but I have not
tried reverting it.
