Greetings!
OK, we have another relocation error, it appears.
Here is my disassembly:
0x08686204 <L45+94>: cmpl $0x5,(%ecx)
0x08686207 <L45+97>: ja 0x868676b <L45+1477>
0x0868620d <L45+103>: mov 0xffffff8c(%ebp),%esi

0x08686215 <L45+111>: mov 0x8687e20(%eax),%eax
0x0868621b <L45+117>: jmp *%eax
as compared to yours

The issue appears to be that the code in sfasl.c does not handle the
.rodata section in which recent gcc is apparently placing the jump
table addresses used by the switch statement. We need the analogous
RODATA_NSCN in ext_sym.h, plus logic to setup a s_start_rodata in
struct sfasl_info in sfasl.c. Check out objdump -r and objdump -d on
clmacs.o.
I wonder how many other sections there are like this. Just one more
piece of incentive to try to centralize around bfd on mingw at some
point. sfasl.c needs serious cleaning at the very least I think.
Take care,
