I get the same problem with a file tst_math.c only containing '#include 
<math.h>':

% m68k-coff-gcc -traditional -fno-builtin -m68000 -c -o tst_math.o 
tst_math.c
In file included from tst_math.c:1:
/usr/lib/gcc-lib/m68k-coff/2.95.3/../../../../m68k-coff/include/math.h:26: 
syntax error before `union'
/usr/lib/gcc-lib/m68k-coff/2.95.3/../../../../m68k-coff/include/math.h:26: 
warning: array `__infinity' assumed to have one element

The C file and the output from
m68k-coff-gcc -traditional -fno-builtin -m68000 -E -P -o tst_math.i 
tst_math.c

are included.

Actually, "-traditional" seems to be the problem. I'm wondering if I can 
make do without it (my code is not ANSI compliant.)
