We (LDC) use the GNU as on MinGW as well, as the LLVM integrated 
assembler doesn't support emitting the Dwarf EH tables into COFF 
files yet. So, you should be good to go in theory, although the 
target config handling code you mentioned might also need some 
adaption – I haven't really looked at that part of GCC at all yet.
