+
+ * read.c (float_cons): Simplified parsing logic. If

+ with a warning.
+
+ * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust

+ need md_pcrel_from for a PC relative relocation within the same
+ file).
+ * config/tc-m88k.c (md_pcrel_from): Corrected return value.
+ (omagic): Removed unused variable.
+
+ * Preliminary support for m88k-coff.

+ m88kcoff.
+ * config/m88kcoff.mt: New file.
+ * read.c (lex_type): New macro LEX_AT to set lex type of '@'.
+ (pseudo_set): Handle difference of symbols in different fragments

+ * symbols.c (resolve_symbol_value): Resolve difference

+
+ * Changes to keep a full expression as the value of a symbol, not
