Fix in 4.4.0.
I was getting:
.LASFDE1:
.long .LASFDE1-.Lframe1
.long .LFB2-. <<<
.long .LFE2-.LFB2
4.5.0 configured right:
.LASFDE1:
.long .LASFDE1-.Lframe1
.long .l...@rel <<<
.long .LFE0-.LFB0
dw2_asm_output_encoded_addr_rtx =>
#ifdef ASM_OUTPUT_DWARF_PCREL
ASM_OUTPUT_DWARF_PCREL (asm_out_file, size, XSTR (addr, 0));
#else
dw2_assemble_integer (size, gen_rtx_MINUS (Pmode, addr, pc_rtx));
#endif
<no other hits>
C:\src\gcc-4.4.0\gcc\config\i386\sol2-10.h(45):#define

} while (0)
#endif
