On an i386-freebsd4.10 machine, using gcc-4.0.1 to compile gdb-6.3, I
get a compiler error.  The same problem still exists on gdb mainline.

../../gdb-6.3/gdb/i386fbsd-tdep.c:48: error: static declaration of
‘i386fbsd_sc_reg_offset’ follows non-static declaration
../../gdb-6.3/gdb/i386-tdep.h:190: error: previous declaration of
‘i386fbsd_sc_reg_offset’ was here

The fix is trivial.  We just need to delete the static keyword from the
i386fbsd_sc_reg_offset definition in i386fbsd-tdep.c.

I've attached the patch for gdb-6.3, which also applies with a small
offset to mainline.  OK for mainline?  Do you want it on the gdb-6.3
branch also perhaps?
