-        * config/tc-arm.h:  Add definitions for OBJ_ELF.
+	Start of changes to remove mdebug section from mips*-elf
+	Based on MIPS_STAB_ELF definition
+	* acconfig.h: undef if not configured
+	* config.in: undef if not configured
+	* config/mips-elf.h: only set ECOFF debugging if not stabs-in-elf
+	* config/tc-mips.c (s_ent): set BSF_FUNCTION
+	* stabs.c (s_stab_generic): flush frag
