to parse debug files generated by MS tools - moved into coff.c (and out of msc.c) the COFF handling - cleaned lots of types (add consistency across structs) - versioning of some defines and types (to follow MS tools evolution) - enhanced V2 of symbols parsing (some more types recognized, support of imported .pdb files) - added support for newest .pdb format
