Unfortunately 3.1 (i'm trying the 2002-01-07 snapshot) doesn't currently
build on hppa. It dies with:

stage1/xgcc -Bstage1/ -B/usr/hppa-linux/bin/ -c -DIN_GCC    -g -O2 -W
-Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes
-Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H    -I. -I.
-I../../src/gcc -I../../src/gcc/. -I../../src/gcc/config
-I../../src/gcc/../include ../../src/gcc/c-lex.c -o c-lex.o
../../src/gcc/c-lex.c: In function `lex_number':
../../src/gcc/c-lex.c:1293: Internal compiler error in
dwarf2out_frame_debug_expr, at dwarf2out.c:1535
Please submit a full bug report,
with preprocessed source if appropriate.
